Existing fabrication facilities for PC's for imaging MCP detectors Dr. O.H.W. Siegmund Experimental Astrophysics Group Space Sciences Laboratory University of California at Berkeley

MCP Image Tube Processing Facilities Industrial Photonis - up to 50mm / night vision Photek - custom to 150mm Proxitronics - custom to 40mm Hamamatsu - mostly small format ITT - night vision American Electro-Optics - night vision Northrup Grumman - night vision Academic UC Berkeley - Siegmund (>120mm) National Lab capabilities ?? Other ??

Night vision companies are essentially geared up for one product and currently very busy European smaller companies have varying capabilities, Photek has most experience with larger tubes. Hamamatsu has small MCP tubes & normally avoids devices that are not commercially viable Photonis has processing facilities in Lancaster PA (Planacon) capable of large tubes, mostly smaller (~40mm) devices in Roden & Brive Industrial

Facilities for development and fabrication of detector systems, both open face & sealed tube Photocathode development and testing Microchannel plate testing Readout anode design and test Electronics development Sealed tube production Environmental testing UC Berkeley / Siegmund

UCB - Facilities and Resources TIG welding Vacuum and N 2 storage Hi-pot, & vacuum baking stations Precision component cleaning station Plasma cleaning Metal electroding evaporation station Leak checker Class 100 assembly stations Many steps are needed to prepare, process and seal MCP image tubes Of necessity this demands a series of facilities to prepare the correct materials

UHV Tube Processing Stations Transfer type facilities with detector test capabilities For processing and measuring II-V cathodes with monochromator For processing and sealing multialkali cathodes in MCP tubes

Tube Processing Facilities Leak Checker Tube facilities and oven

Detector Imaging Electronics and Diagnostics Test Equipment
