Laszlo | General | E127 beamtime overview | |
Here is a representation how was the time management during E127. The time, what we could spend with measuring the 118Te(pg), was ~20% comparing to the given 6days. |

Laszlo | Detectors | Detector movement from HKR | |
To move the detector remotely from the HKR:
-go to a desktop of a HKR computer
-right click: "App Launcher PRO"
(-you have to give some password at this point?)
-within the program go to "Development->ProHelper"
-write the name of our slow control unit in the field Nomen: "GE01DD4AS"
-There are 4rows, the middle two called: "Read props", "Write props"
-In "Read props" open "rposiabss" -> if you hit here the refresh button it will show only the SET position
-In "Read props" open "rposiabsi" -> if you hit here the refresh button it will show the REAL-TIME position of the detector
-In "Write props" open "wposiabss" -> here you can set the absolute position of our detector (one click is already enough to execute the command).
most OUT of the ring position: -10613 [0.1mm] in absolute
most IN into the ring position: -7 [0.1mm] in absolute
The value can have as big step size as we want contrary to relative movement, when you are limited to something like 20cm.
To close the program just simply hit the "x" buttons. |

Jan | Detectors | DSSSD positioning | |
To find a good Si position, we need to follow a procedure similar to this:
1. Si in max-in position
2. find distance of beam by scraping with detector from inside
--> zero position
3. from this zero, we need to set a distance of about 1.5 cm to the inside (as shown in the sketch below)
It is likely that this position is not compatible with the complete ESR cycle (e.g. we scrape beam with det. during deceleration).
The solution is to move the beam closer to the detector after deceleration. There are two feasible methods to do this:
A. make a local bump in the dipole
--> check new zero and det. position again, as sketched above
--> in 2016 this method didn't allow to go close enough to the detector, eventually we used:
B. global orbit change (by magnet ramp) + target bump (to keep overlap)
--> this takes a bit more time to set up and also the cycle will be longer at low energies (critical due to life-time)
--> method A is preferred, but might not be strong enough
This needs to be checked and repeated for each new beam setting. |

Laszlo | Detectors | DSSSD and SCRAPER position estimate for Xe and Te experiments | 2020 |
We don't know the exact absolute positions of the detector (+scraper) and the beam. However, what we have to know is only these two relative positions respect to each other. To get this distance I use two methods:
1, combining the infos from the set position during the beamtime + the measured pg peak position on the detector. The pg peak position is defined only by the eye (because of the low number of counts in every case, it doesnt make much sense to make fits). Since we rely on the detector resolution, we would be never more accurate than ~ +/-1.5mm anyhow. The active area of the detector is 49.5x49.5mm2 with a 45° tilt in y.
2, MOCADI simulation of the beam and the pg peak. This is used only as a crosscheck.
3, The scraper had a small angle in y direction causing ~0.5cm shift to the upper direction. the length of the scraping edge is 7cm
-124Xe with scraper measurement:
- measurement
d1 = moved back from beam = 15 +/-.5 mm
d2 = DSSSD frame width = 8.85 mm
d3 = pg center on DSSSD = 7-7.5 bin = 21.7-23.2 mm = avg = 22.5 mm
--> pg from beam in x = -46.4mm +/- 1.5mm
--> pg on DSSSD from center ~ -3.28mm +/- 1.5mm
- simulation
x = -46.5 mm
y = 0 mm
- detector active area position
x = (-73.35mm) - (-23.85mm)
y = (-14.2195mm) - 23.5125mm
- SCRAPING: x=-35mm +/-0.5mm away from beam
y=(-20mm) - (40mm)
-118Te:
- measurement
d1 = moved back from beam = 16 +/-.5 mm
d2 = DSSSD frame width = 8.85 mm
d3 = pg center on DSSSD = 7.5 bin = 23.2 mm
--> pg from beam in x = -48.05mm +/- 1.5mm
--> pg on DSSSD from center ~ -3.28mm +/- 1.5mm
- simulation
x = -48 mm
y = 0 mm
- detector active area position
x = (-74.35mm) - (-24.85mm)
y = (-14.2195mm) - 23.5125mm
- SCRAPING:
x=-35mm +/-0.5mm away from beam
y=(-20mm) - (40mm)

Jan, Laszlo | Detectors | DSSSD - 1st movement - realignment | |
We moved the new detector installation for the first time slowly into the dipole chamber.
The alignement seems to be pefect, no distortion or vertical movement of the detector-arm was observed from the window flange.
The vacuum on the detector side went up from 2e-10 mbar to about 5e-9 mbar.
On the ring side it was 3e-11 mbar befor and 1e-10 mbar after movement.
The extreme positions possible (Endlage) are:
max out: -10613
max in: -7
These are the absolute positions in units of 0.1 mm
It has to be noted that after bakeout a realignment of the detector was needed in order to have it centered in vertical dimension. However, this realignment has been only slight turns of the base flange alignment screws. In detail, the two inner "Sechskantschrauben" below the bellow have been loosed slightly, while the outer two have been tightend. Additionally, the small "Madenschraube" on the outside has been loosend by 1/4 turn.
In result the detector could be raised in vertical position by about ~5mm (jugded by eye).
The effect of small turning on the screws is extreme on the detector position! Be careful when re-adjusting. |

Jan | Detectors | DSSD installation and alignment | 2021 |
The DSSD has been exchanged and aligned in
November 2020. After bakeout at 140°C
(externally, 120°C at internal temp. Sensor)
for more than a week, the vacuum in the setup
is roughly 4.5e-10 mbar.
After the bakeout the detector had to be
realigned, it was lower by 1-2 mm. Using the
line laser the realignment was done by
touching only the screws on the far part of
the base of the flange. These screws have been
thightend by about a 1/4 turn after releasing
the headless positioning screw accordingly. |

Jan | Calibration | DSSD X/Y channel mapping | 2021 |
During the detector test test measurements with alpha source the allocation of the 16 X- and 16 Y-channels has been checked.
For the following final allocation, it is always assumed that the (horizontal) y-strips are placed to face the beam directly, while the (vertical) x-strips are on the backside.
Now, all cables from the preamp to the ADC/TDCs are either labeled BLACK (= X-strips, pos. signals) or labeled RED (= Y-strips, neg. signals). These red or black connections should be kept consistently in order to ensure a well known orientation of the DSSD during the experiment. The test run Si2_run006.lmd was taken with this final assignment and serves as reference.
BLACK LABEL > X1 to X16 > pos. MSCF > ADC/TDC ch 0-15 > 50 Ohm resistor at preamps HV-input
RED LABEL > Y1 to Y16 > neg. MSCF > ADC/TDC ch 16-31 > neg. bias voltage at preamps HV-input
Additionally, the RED label indicates the section on the preamp to which negative bias voltage should be applied. |

Laszlo | Calibration | Counts in the K-REC peaks | |
3 datasets were investigated:
-124Xe with Scraper (2. Xray calibration parameters needed)
-124Xe without Scraper (2. Xray calibration parameters needed)
-118Te with Scraper (1. Xray calibration parameters needed)
I looked all the 35°, 90° and 145° detector spectra:
-For both Xe measurements all 3 detector signal can be evaluated
-For Te beam one can see only in the 145° detector spectra the Kalpha and K-REC peaks (with high uncertainty). For the 35° probably the detector was simply not sensitive enough for such low beam intensities. For the 90° case, I am much surprised, the peaks supposed to be there the most prominent of all. In the spectra, I maybe can recognize a peak at ~27,8keV, but this is even in best case only the Kalpha peak. At the range of the expected K-REC (~40keV), there is a bit of increase in the background overlying the peak. This background increase is also in the background spectra. Also probably this twisted cables issue between 90° and 145° didn't help much. I think anyhow, that maybe this must have some noise related origin. I can remember that the cables (despite all of our and Uwe's tries) were not well grounded, the noise level was kind of floating.
In general, I would also remark that we can see some peaks >60keV in the background, but these luckily don't disturb us.
To evaluate the Xray spectra I used the following algorithm:
1, for each type of beams I used the list of event numbers in the next entry (to exclude "bad" events)
To get the Kalpha and K-REC and other peaks I used the condition trigger==1 (jet ON)
To get the background spectra, I used trigger==2 (Jet OFF). The background spectra is only used to see that there is no underlying peak structure below K-REC. To subtract count, the background histo was NOT in use.
2, While using a well-suiting number of bins, I plot the JetON and JetOFF histos.
By eye I choose the range of the K-REC peak and the range for the background fit on the JetON histo. Ofc range_bckgnd > range_peak.
Simultaneously, I check on the JetOFF histo that both, in the fit-range and in the peak-range, there should not be any peak structure visible.
3, For the fit-range in JetON histo, excluding the peak-range, I fit a linear function, m*x+b. For each bin in the fit-range I subtract m*bin_center+b value from the bin content. After the subtraction I check if I got spectra looking like a single peak sitting on a zero
line.
4, To get the K-REC counts, I sum together all the bin values for each bin of the subtracted histo within the peak-range. For the error calculation, I use Gaussian error prop. The uncertainty of the JetON histo counts = sqrt(counts). Also for the subtraction I make the
error like delta(m*bin_center+b)= sqrt(m*bin_center+b) instead using the uncertainty of the fit parameters. This second one wont make much sense, since the slope of the linear fit is usually close to 0 --> the errors grow unrealistically big.
Based on the algorithm above I got the following counts:
-124Xe with Scraper:
35°: 174 +/- 15
90°: 21299 +/- 150
145°: 2104 +/- 52
-124Xe without Scraper:
35°: 65 +/- 9
90°: 7792 +/- 91
145°: 728 +/- 31
-118Te_part1 with Scraper:
35°: -
90°: 427 +/- 40
145°: -
-118Te_part2 with Scraper:
35°: -
90°: 741 +/- 48
145°: -
-124Xe_lowRate with Scraper:
35°: -
90°: 2121 +/- 52
145°: - |
