Description 'Beam-X Switch' family from Burroughs. To reduce the size of the previous beam switch tubes, Burroughs moved the magnetic source inside the electrode structure; 10 small magnets were mounted into the tube, one for each counting position. The Beam-X family had no pin available for zero reset feature.
Glass envelope with 26 pin base, external magnetic shield. BX4000 is the low-voltage version of BX2000; 1MHz counting speed, 30V target voltage, 1mA target current.
Operating principle of trochotron.
