Objective log on perceived issues. (As a benchmark, I enumerated 17 such issues on my previous RIB experiment March 2017.) In no particular order... 1) Sun PC: Cannot properly connect to internet, disallowing SSH access Important for external monitoring Better to control DAQ from ISOLDE data room in case of ISOLDE issues Connecting to CERN network screwed with DNS, borking local DNS hence DAQ Double mouse clicking often skipped run numbers 2) Vacuum: Barely acceptable, and manual gate valve leaked! Keep in mind, interlock system showed higher than true values 44Ti requires a gas cell and vacuum load may increase considerably (Chamber needs gas-feedthrough lines and gas-flow control system) Cooling lines are known to leak badly 3) SSDs: HI detector leak current increased considerably during the run Noisy n-n sides To be discussed 4) Scalers Scalers were made with noisy n-n sides, making interpretation confusing We lacked LEMO cables to provided summed p-n scalers 5) Decay halflife A simple handheld monitor turned out to be effective for 59Cu That won't work for 44Ti ... 6) Unused aparatus should be minimized (Time & money) Photodiodes ZnS screen / camera Manual gate valve (see above) 7) Shift plan/schedule No definitive plan -- need pre exp. meeting Shift schedule became arbitrary, w/ several flip/flops RP requirements limited access to chamber 8) Shift work Run log was made with short notice Style may not be ideal for data analyst Copy/paste errors et al were observed Deadtime log was suggested to be added (Other issues might be circumvented w/ SSH access to Sun PC) 9) Purpose Detail & motivation of exp. was not clear to all members 10) Faraday Cup Data taken by TIMBER system, which is better to integrate w/ our DAQ Strange non-physical fluctuations which we like ISOLDE team to resolve Timestamp differences of Sun PC and TIMBER PC? 11) Silena HV module Module was found to falsely report applied bias 12) Alpha calibration / pulser walkthrough Lacking prior to experiment owing to manpower and technical difficulties 13) Sort codes and simulations It was common to discuss received vs. expected data w/o fast clear answer
