Re: items to give away

Sorry; was supposed to be "off list"; however, now you all know one
use.  Another is the Busch e/m * method.  Any electrostatic deflection
kinescope works.  The 5BP1 was used in early o'scopes, RADAR, and
probably TV.

PSSC and Berkeley Physics Lab., inter alia.

p.s. the rejuvenation device is (at least the ones I've seen) is a 6 V.
transformer to apply a sl. higher EMF to the heater to compensate for
loss of emission.  The low work function coating diffuses into the W.
The higher temp. results in more at the surface, so I've read.
