When regaining the window the voltage limit was applied and the detector began to ramp down The set voltage was reset to 100V and bias was regained. Total time with less than 100V was around 30sec 14:28 DTAS and BigRIPS stop AIDA on run R2_386 DTAS Starts file 66 BigRIPS run 2026 AIDA on file R2_387 14:32 Bias and leakage currents ok - attachment 21 15:07 Rate spectra showing no spikes in DSSD 3 System wide checks 15:08 DTAS and BigRIPS stop AIDA onfile R2_393 BigRIPS chaning slit positions 14:14 DTAS starts file: AIDA on file R2_394 BigRIPS file 2027 (In control by bigRIPS) 15.30 TAS and BigRIPS stop AIDA onfile R2_396 Encoding: HTML ELCode plain Suppress Email notification
