- Start DACQ computer: OK!
- Create directory: /data/1810Preparation/
- Copy last configuration RIBF139 file:  171119_1126_Conf_BrikenFullYSO.xlsx
- Return PB-5 pulser into crate and set parameters
- Star all crates: OK!
- Start DACQ: OK!
- Rename configuration file and edit to eliminate YSO related parameters
  New Config file: 181016_Conf_BrikenFull.xlsx
- Start 3He tube HV: power the ethernet hub, power the pixie PC,
  edit the hvmon.conf file (only tubes active), run hvmon: OK!
- We realized that current and voltage of VME crate 1 was oscillating.
  We pulled out V1A7 (not used) and it became stable: seems that we are at the limit of 
  power supply: OK!
- We put the 252Cf source in and check gain match:
  only (the gain of) three tubes moved slightly since the last run (one year ago)!
  He006, He134, He135 -> new calibration: OK!
- We move SIS3820 clock from internal to external frequency:
  Setup UK Tektronix clock: 25MHz, square signal, 800mVpp, -400mV offset
  Plug in Lupo module (VME1 crate): OK!

ISSUE: the current placement of the table supporting the MUSIC chamber
is too close to the VME1 crate and one of the modules (V1A4) 
cannot be extracted in case of failure. However V1A7 is unused
in this run and can be used as replacement.
