Jan | Detectors | bakeout at ESR setup | |
The bakeout for our detector setup has started on the evening of 27.08.2019
We have a temperature sensor in the vacuum next to the detector.
The goal is to maximize bakeout temperature, while not going above 125°C at the detector/sensor.
Here is a daily protocol of temperatures and vacuum pressure
T_12 is the set value of the 1st and 2nd controller device
T_34 is the set value of the 3rd and 4th controller device
T_56 is the set value of the 5th and 6th controller device
T_sens is the temperature measured by the sensor close to the detector

Laszlo | Analysis | simulations on 118Te+p | |
I have made some simulations at 8AMeV, 7AMeV and 4AMeV energies for the main 118Te + p reaction channels. For the
Rutherford simulations credits to Yuanming! For each energy there are 3 simulations: without the scraper, with the
scraper (online), scraper (online) + E-truncation (offline). The scraper is treated as an "ideal scraper" meaning
that there is no scattering at the edges (maybe worth a GEANT4?). The slit position is at -3cm from the beam, the vertical
length is 7cm (centralized). The following channels are combined in the
simulation:
-8AMeV:
Rutherford
pg channel, 5cascade model. Photon emission is treated isotropically
pn channel, including: -->gs, -->1-->gs, -->2-->gs, -->3-->gs, -->3-->1-->gs, -->4-->1-->gs, -->5-->3-->gs,
-->5-->3-->1-->gs, -->5-->4-->1-->gs decay chains with their weights. Neutron and photon emission is treated isotropically.
-7AMeV:
Rutherford
pg channel, 4cascade model. Photon emission is treated isotropically
-4AMeV:
Rutherford
pg channel, 3cascade model. Photon emission is treated isotropically
The detector position is -2.5cm from the beam in the radial direction and centered vertically with a 45° tilt.
The cross section values for pg and pn, the pn channel mixing, and the pg cascade number is based on TALYS simulations.
The other two input parameters are the luminosity and the measurement time. For the simulation, a little
pessimistic (or realistic?) scenario is taken: L = 10^24 cm-2s-1, and t = 10^4 s. From this values, from the N=CS*L*t
equation, the pg counts (based on the TALYS
cross sections) are the following: 8AMeV ~267, 7AMeV ~163, 4AMeV ~5! This means that to reach the Gamow-window
energies is challenging, but with a well-working scraper it is not impossible to reach.
As it is visible, the 8AMeV 118Te(p,g) case is very similar to the 7AMeV 124Xe case. The p,n threshold is
somewhere ~7.5MeV. |

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. |

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, Laszlo | Detectors | setting up the DSSD with beam | |
This is a brief how-to about getting the DSSSD set up with stored beam and target in the ESR.
The main goals
1. adjust timing signals to TDC-range
2. adjust energy signals to ADC-range
3. optimize energy resolution
The signal chain is the following:
det [32ch.] > preamp [2x16ch] > 2x MSCF shapers [16ch] |

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. |

Jan | Detectors | x-ray background from BaF | |
The BaF2 detectors planned to be installed at the target induce an additional background in the x-ray detectors sitting below inside the target chamber.
We made test measurements with an x-ray detector for estimating the background in the region of interest for our K-REC measurements (35 to 50 keV).
For the interval [35-50 keV]:
Normal background level: 0.065 (s*keV)^-1
BaF2 in 5cm distance: 0.078 (s*keV)^-1
This is an increase by about 22%
Assuming an increase by 100% induced by 6 BaF2 in the vincinity of the Ge-detectors this seems acceptable.
However additional BaF-induced peaks are also visible at ~30 keV and ~60 keV. While these are not in the region of interest for the K-REC, we need to be aware of them!
spectra are available on the Frankfurt exp-astro Server at /home/glorius/e127/ |
