Sun Oct 2 15:03:11 2016, CG, TD, Problems compiling AIDAsort program on aidas1
|
I have been trying to compile the sort program I have been working on in Edinburgh so I can work on it locally
while at RIKEN.

Tue Jun 6 07:44:19 2017, TD, Preamplifier waveforms 25x
|
Preamplifier waveforms sampled by 50MSPS, 14 bit ADC
|
|
Wed Oct 1 15:41:07 2014, Patrick Coleman-Smith, Power supply filters #3
|
Measuring the signal at the FEE64 end.
+5v , -6v , +7v, +7v
The two other 'scope channels are connected by FET probes to the FEE64. I now see there is a ground connection.... so i will remove it and re-measure |
|
Wed Oct 1 13:28:03 2014, Patrick Coleman-Smith, Power supply filters
|
The new pcb for the power supply filter arrived.
I assembled the components ( after finding the whoops ) and connected it to the bench power supply for nnaida2.
nnaida2 functions just about the same as before but the power supply filter results seem amazing. |
|
Wed Oct 1 15:15:32 2014, Patrick Coleman-Smith, Power supply filters 14x
|
2.0.L FWHM:14.26
2.15.L ( 270pF ) FWHM : 119.04
(ooops found the 'scope channel was on 20Mhz BW filter ) |
|
Fri May 13 13:27:50 2016, patrick Coleman-Smith, Power supply changes and blowing fuses !
|
Reading about the power supply changes and the requirement to replace fuses leads me to be concerned.
I think the power being changed is the AC input to the FEE64 power supplies.
Which Fuses are failing ? |
|
Fri Nov 4 08:10:46 2016, CG, Pb bricks upstream
|
| Stack of Pb bricks upstream of AIDA+BRIKEN to protect from incoming beam. |
|
Wed Mar 1 16:42:06 2023, Further results from Mezzanine bench tests, PJCS
|
Carried out some further work on failed mezzanine modules.
Inspected them externally and removed the copper block, internally with a bench microscope.
Found two obvious faults ..... broken components with scrambled pcb tracks. |
|
Mon Jun 17 03:01:04 2019, CA, TD, OH, PID plot and selected isotope implantation rates
|
PID plot produced from 2 hours of merged data - attachment 1
Z on y-axis, A/Q on x-axis
