184" CYCLOTRON
VERTICAL D. C. ELECTROSTATIC DEFLECTOR

By Duane Sewell

Experiment done by: J. Vale, L. Houser, R. Watt, W. Chupp,
A. Reyenga, and W. Grimshaw "


INTRODUCTION::

It was found from previous experiments that the beam was rapidly .spreading vei:
cally at approximately the 81" radius. It was thought that if a vertical deflector was i":
placed below the median plane at this 81" radius, the beam could then expand tob the :...
deflecting channel. Once in the deflecting channel it could then be deflected rapidly i .';
region in which a magnetic shield (or deflector) could be used to bring the beam. out of thd':
cyclotron.

RESULTS

1. Approximately 60 kv could be held on the high voltage electrode of this deflector. i4ie.:

2. On one occasion it looked as if an ionization chamber mounted on the probei:Was: det t. '
ing a small deflection of the beam. However, this could not be verified on subseq6oi -
runs.

3. The best detection of the beam deflection was made by mounting X-ray film. o.the: pk9
and exposing it to both the undeflected and deflected beam. .

4. There was considerable sparking between the HV electrode and the .002" copper foil :.;
The copper foil was warped badly when the deflector was removed; this had apparently "":
been caused by the lodal heating from the sparking. The 0.002" copper foil supported 4"
in this manner is hot suitable for this job.

5. The copper foil was very radioactive after a short run.
