sPHENIX EMCal discussion

Shannon, Nathan-

The basic abstract looks fine, however, I would like to suggest that you add a sentence or two explaining why they need to be sorted to operate at the same voltage (balanced gain in each tower) and also indicate which SiPM has been selected for the sPHENIX calorimeters, Hamamatsu S12572-015P.

Hi all,

My student, Shannon Dancler, plans on attending the Conference Experience for Undergraduates (CEU) at DNP this October and would like to submit the abstract given below. Any and all suggestions are welcome. The deadline for abstracts is August 1.

Many thanks,

Nathan

SiPM Testing and Sorting Simulation for the sPHENIX Collaboration

Shannon Dancler, for the sPHENIX Collaboration

The sPHENIX collaboration studies heavy ion collisions in an effort to better understand the strong nuclear force. The collaboration has proposed a new detector to be built at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory.  The electromagnetic and hadronic calorimeters will use approximately 100,000 silicon photomultipliers (SiPMs) to detect light from showers produced in the calorimeter by particles produced by the collisions. There will be four SiPMs per calorimeter tower, all operated at the same voltage. One of the objectives of my research was to test the operating voltage of an SiPM by measuring single photoelectron peaks shift with bias voltage. The second objective of my research was to develop a method to sort the tested SiPMs with similar gain into groups of four. In this poster we will give details of the test stand, show gain measurements, and the results of the simulation used to develop the sorting method.
