C. Morrell et Pp. Manning, AN AUTOMATIC LIQUID-NITROGEN FILLING SYSTEM FOR USE WITH SOLID-STATE X-RAY-DETECTORS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 381(2-3), 1996, pp. 560-566
An automatic system for the filling of liquid nitrogen-cooled X-ray de
tectors is described. A novel feature of the system is the pre-cooling
of the transfer tube from the nitrogen source to the detector when fi
lling is initiated. This avoids some problems inherent in commercially
-available systems. The control electronics center around on inexpensi
ve microcontroller chip. This allows for the inclusion of safety featu
res, whilst keeping the circuit construction very simple and straightf
orward.
