You should not denigrate PhotoMultiplier tubes. They are virtually perfect, almost noiseless, detectors. With the right photocathode, they are capable of QEs 50%, spectral response from the VUV to near IR, and dark counts 1 PPS, with maximum count rates 10 MPPS. Thay can easily have current gains of 10E+6 -John Thanks, John It's quite clear that at least one far eastern nation, need I name it? is going for domination of space, meanwhile feinting with such useless stuff as old rotted carriers and the like, nothing up my sleeve, trick the first, meanwhile building its own gps fleet, hardened i'll bet, and reaching for the moon.

I thought it criminally stupid when the US shut down its LORAN service. I thought that Galileo, with its eLORAN backup and distribution of WAAS data, was brilliant. For aviation the US kept its antiquated network of VORs and discarded LORAN, even though the annual maintenance and operation costs were about the same for both. And LORAN provides more accurate positioning than VOR (but not DME-DME and no one bothers to use DME-DME, go figure). -- Brian Lloyd, WB6RQN/J79BPL 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.com +1.916.877.5067 ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] Now For Something Completely Different...GPS Security
There was a lot of work done on GEN III NV devices. They use GaAs photocathodes w/ high QE. The same photocathode works for PMTs. Detecting single photons is duck soup w/ a PMT. With modest cooling, you can get the dark count down to 1/minute or better. -John = On Fri, Feb 14, 2014 at 7:45 AM, J. Forster j...@quikus.com wrote: You should not denigrate PhotoMultiplier tubes.
