The Large Area Picosecond Photo-Detector Collaboration (LAPPD) is currently developing a large-area, modular photo-detector system composed of thin, planar, glass-body modules, each with two 20cm x 20cm ALD-functionalized MCPs in a chevron geometry. The collaboration is working closely with industry partner Incom, Inc. towards the commercialization of this technology. One of the major challenges has been to successfully seal a top window to the hermetic glass package module. The collaboration is pursuing multiple sealing techniques; one a hot solder sealing technique and a second thermo-compression sealing technique. In this talk, I will present results from a thermo-compression seal of a top window to a 20cm x 20cm glass package module with a pump out port for leak checking the seal and describe the path towards commercialization of the 20cm x 20cm devices with Incom, Inc. As an intermediate step towards building a full system for making 20cm x 20cm devices, but independent from the LAPPD collaboration, Argonne has also developed a small form-factor (6cm x 6cm) photodetector development facility consisting of a four vacuum chamber system: loadlock, bake and scrub chamber, photocathode deposition chamber, and sealing chamber. Successful thermo-compression sealing of the 6cm x 6cm photodetector prototypes at the Argonne development facility has been accomplished in the sealing chamber. The entire system has recently undergone a bakeout and is currently achieving an ultra-high vacuum base pressure throughout the system with photocathode fabrication underway. An overview of results from the first working 6cm x 6cm active area detectors based on the ALD micro-channel plate, all glass body technology will be presented as available.
