run number 586
Thanks to MCC we have about 3 hours stable beam for this run.
beam current ~ 5nA, beam position(2c24) : x = +- 0.4mm , y = +-0.4mm ;
Dynode total sum signal is good enough to equalize HyCal PbWO4 modules;
Equalized 31 modules from W1 to W31, most of HV are about 1100V for 150mV Dynode total sum signal and have ~3000 ADC channels of Anode.
Estimate still need  ~50 hours beam time to finish 1100 PbWO4 modules.
