A list of parts available at low temperature
We are studying electronics parts provided as commercial products available at low tempareture such in the situation in liquid nitrogen, although their feature may change from that at room temperature. Our purpose is to find small and reliable parts used to develop photomultipliers that are operated in liquid Xe for the construction of a new type of calorimeter with good energy, position and time resolution. Below is a list of parts which we studied.
