In compliment to Liliana's plots, this is the summed spectra I calculated from 0338 to 0507.

Some plots of statistics up to now

made sure that the extra 20dB amplifier is off.

this picture is after scraping by helmut, showing the 410 MHz detector, that is we would expect an isomer where the marker M1 is, i.e. at 2.2kHz on the left side, which we unfortunately don’t see (yet).

a reference schematic of the peaks on 410 MHz (211th harmonic) and 245 MHz (126th harmonic)

Scraper settings have been played around with to try and remove satellite lines...

Helmut has now set scraper id GE01DS_H at -45mm (in position)

Image of injection structure attached... 72Ge is the isotope in focus on the RSA

Opened TE4 slits again to +/-10mm.

Then we tried different scrapers:
in south arc outside: E02DS3HG, cuts at ~ -25mm, at -15mm gone, leave at -35mm.

on straight section: EEXDS2HA cuts at ~ -25mm, leave at -25mm.

EEXDS1HA, closing it to -25mm revealed a double peak structure with distance just like the wanted isomer (-2.2MHz at h=211).
But it is present on all intense peaks at the same distance, so it must be an artefact of a strange isochronicity curve.
Closing it to -15mm even had only the smaller lower frequency line survive.
But then it must be also possible to have only the stronger line. leave at -25mm

This worked with scraper in north arc E01DS_H which can cut from both sides.
The insie can ve iused to cut the lower Brho, 
at -50mm still two peaks, at -45mm left peak almost gone, -40mm left peak gone but right still intense, leave at -40mm.

-> Lower Brho seems to be clearly related to lower frequency, higher Brho side is not so clearly related to frequency.

Measure in this setting, nice void at wanted frequency. But no isomers appear so far.
 

At the moment we see a second peak to the left of each intense line. 
The distance between the main peak and the shadow is roughly the same for each peak.
This hints to a sharp fall in the isochronicity curve.
Helmut now tries to remove these shadows by using different scrappers. 

RFQ fall-out (HKR working on it...)

This is a comparison of I_Raw/Q_Raw between different reference level. The range of NTCAP ADC is only 2^15 bit. So signals (I_Raw and Q_Raw) should 
not be outside ADC range. It is clear that there is not point outside the ADC range when using reference level -30dBm.

Reference Level: -30 dBm.

We think we see the frequency range of A/q=2.25 at 243.1 MHz.
This would correspond to L=108.2m and E=386.4 MeV/u (gamma_t = 1.3955) at h = 126.
Path length is a bit short, for L=108.4m it should be 370.6 MeV/u. 
(later reanalysis shows the measured frequency corresponds to 108.38m, which is like expected)

We closed scrapers on arc outside and straight section outside to limit Brho from both sides.
GE02DS3HG = -35mm, GEEXDS2AH = -25mm

Expected frequencies see below:

Beam is secondary beam now. The intensity is lower. Change reference level to -50dBm.
Carrier frequency:245MHz
IQ rate(S/s): 20M.
Reference Level: -50 dBm.

parammodi exports, E-SIS = 441.0 MeV/u with Be-1840 mg/cm² target in, isoc. ESR, at least we see fragments

The two grids do not work very well, one x position is opposite to the other.
But at least a guidance for the future, this was good injection of 78Kr with a thick Be target.

gamma_t = 1.3955
Br(72Ge) corresponds to 6.79575 Tm
E (Kr) at Br(72Ge) = 392.9 MeV/u
ESIS = 467.45 MeV/u (pre-drilling, after 1.8 g/cm2 target)
ESIS = 440.98 MeV/u (final energy for 72Ge)

-during setup, a 20 mm offset in the TE line was observed. Beam centered via changing the Br of the beamline (~4 MeV/u up). Optimized pre-drilling transmission ~20% (with thick target)

NTCAP was stopped at 17:34 for the optimisation purpose.
NTCAP started again at 18:20 with the change in Reference Level (dBm): 0
