R4 stopped and moved to the next run R5.

Lithium 3+ beam is not feasible at sufficient densities so we are switching to D+ at a beam energy of 0.75 MeV/u. A measurement of d+p at this energy would produce 3He at energies of ~900 keV. 

The current threshold (slow comparator) has been 1 MeV (0x64). We lowered the thresholds in all FEE modules to 200 keV (0x14). ADC rates look fine in all FEEs (~tens of Hz) except in aida 15 and aida 16 which was ~several hundred kHz. Data rate to disk was 1.2 Mb/s

We increased the threshold in aida 15 and 16 only to 500 keV (0x32) and rates in aida 15 and 16 have dropped to <20 kHz. Data rate to disk now 220 kB/s.

11:00

Edits to the CARME sort code have been made. EyEx energy cut for online monitoring reduced to 100 keV. Multiplicity cut applies to lowEnergyEy, lowEnergyEx and lowEnergyXY histograms. Multiplicity cut considers only single strip events.

Only low energies observed in the energy spectrum. Looks a bit like the low energy noise observed in our previous runs with no/very few counts above what would be beam energy (~7.6 MeV)

Note the xy plots are not all orientated correctly (strips are correct in the sort code but root axis need to be flipped - I can;t remember how atm). The part of the plots with counts are those closest to the beam.

Spectra still looks the same. I have noticed the right hand side rate is higher than the left. EyEx cut spectrum also looks like much more counts outside of the cut.

I can now see a small peak at 5 MeV in the bottom left dssd. This dssd also has the least number of counts in the low energy continuum.

Summary

All FEE64s appear to be working (except aida05 which has c. 8 missing channels) with pulser - which 
validates the FEE64, ASICs and adaptor PCB.

Electronic noise c. 50keV FWHM for aida01 & aida03 - other FEE64s better/worse.

Preamplifier noise appears to be similar for all FEE64s which may suggest an issue with the test signal chain

The PEXARIA5 card provides equivalent functionality to the VETAR2 VME module that we have used to date.
