15.06 Quick test of AIDA 24cm x 8cm 'triple' DSSSD before dismounting to install 1x bPlast detector downstream of the DSSSD

Water flow, pressure and temperature OK

Power Up OK

All system wide checks OK

DSSSD bias -150V leakage current -5.29uA

ASIC settings 2021Apr29-13-16-00
      FEE64s re-configured to aida01 - aida08 by NH
      aida02, aida04 negative input, all other FEE64s positive input
      Currently unable to specify settings directory for Options so aida06 & auida08 are still defined as negative input FEE64s - need to change ASIC settings manually

slow comparator p+n FEE64s 0x64->0xa, n+n FEE64s 0x64->0xf

per FEE64 Rate spectra - attachment 1
      ADC data item stats OK - attachment 2
      p+n FEE64 rates dominated by 'hot' channels, other channels < 1Hz
      n+n FEE64 rates ~ 10Hz 
      Known issues with aida04 asic #1 and aida10 ( now aida06 asic # 4 ) remain to addressed/investigated

No chnages in performance cf. https://elog.ph.ed.ac.uk/AIDA/906 & https://elog.ph.ed.ac.uk/AIDA/907
