Description
Applications including searches for neutrinoless double-beta decay, stroboscopic
methods in neutrino oscillations, flavor/baryon flow and primary/secondary/tertiary
vertex identification at future colliders, and low-dose whole-body Positron-Emission
Tomography, would benefit substantially from photodetectors capable of covering large
areas with psec-level time resolution and sub-mm space resolution. We describe the
design of a facility for the batch production of large numbers of highly uniform micro-
channel-plate photomultipliers (MCP-PMT) using the “air-transfer” photocathode pro-
cess we have demonstrated on single LAPPD^{TM} modules at the University of Chicago.
The proposed facility uses dual nested low-vacuum (LV) and ultra-high-vacuum (UHV)
systems in a rapid-cycling, small-footprint, scalable batch production facility that is
capable of producing 100 8in × 8in photodetectors per week. The system allows the
use of O-rings or gaskets rather than the usual UHV seals, full access to the modules
for leak-checking before synthesizing the photocathode, and real-time photocathode
optimization with feedback.
