10.30 AIDA setup and DAQ start complete
      writing to file TapeData/NULL/R1

FEE64 Temperatures and Good event statistics ok (attachments 1 and 2)

11.00 results of analyser - shows significant number of timewarps in aida07, and a few in aida01-04

11.24 compared timestamps between mbs and AIDA, agree to 8 digits (attachment 3)

12.49 DAQ and Merger stopped and restarted

Raised slow comparator threshold from 0xa to 0x64

Raised fast comparator threshold (LEC/MEC) from 0xf to 0xff

12.51 Good event statistics: aida08 running at a normal rate

pulser peak (1.8.L) no longer has noise shoulder (attachment 4)

writing to file TapeData/NULL/R2

13.58 stopped writing to file. Pulser frequency increased to 1 kHz

writing to file TapeData/NULL/R3

15.00 file R4 - DAQ startup

17.58 trimmed and re-crimped ground wire on aida08
      lowered pulser freq back to 50Hz
      reduced slow comparator threshold to 0xa, fast comparator threshold (LEC) to 0xf

good event stats ok, aida08 no longer running hot (attachment 6)
      1.8.L and 1.8.W spectra of aida08 (attachment 5)
      pulser peak width now at 55.71

FEE64 temperatures ok (attachment 7)
