Attachment 1 - snoop -d bge1 log following MVME CPU reset
Attachment 2 - VME CPU system console
Fixed MVME2354 CPU RPC timeout when mounting MIDAS filesytem (see attachment 2)
by changing Sun workstation name services configuration file /etc/nsswitch.conf
to remove dns i.e. from
hosts: files dns
ipnodes: files dns
to
hosts: files
ipnodes: files
*Why* this works is a good question ... |

> Faraday cup readout at the end of our chamber should change based on whether or not the target is in and also the 59Cu
beam energy.
>
> The effect could be as much as 10 to 20%. At some point, we should check the Faraday cup reading with the CH2 target
and with the empty target.
For comparison, csd predicts 5.00MeV/u 59Cu?+ -> 4.66MeV/u 59Cu24+ following the 0.5mg/cm2 (CH2)n target

TD | CAEN V767 TDC trigger/channel 0 logic change |
Approximately 5-10% of events overnight were 'bad' i.e. missing TDC data
Checked the CAEN V767 trigger/channel 0 logic (without beam) this morning
and observed that the delayed event trigger was within 20-30ns of trailing
edge of MON2 (trigger accepted). Increased width of MON2 from 100ns to 150ns.
Check whether this change reduces or eliminates 'bad' events when beam
returns. |

ADC offsets calculated using data files R42-r47
ADC gains calculated using data files R26, R30 & R38
Re-sorting data files R26, R30 & R38 using calculated ADC offsets and gains
the 241Am alpha peak centroids are at
E_HI 86 c(3) = 5.380*10/86 = 0.625581
E_alpha 251 c(2) = 5.380*10/251 = 0.214343
dE_alpha 1021 c(1) = 5.380*10/1021 = 0.0526934
Calculate energies (100keV bins) for channel i using
e(i) = INT( c(n) * gain(i) * ( data(i) - offset(i) ) + 0.5 ) |
