184" CYCLOTRON

RADIATION MEASUREMENT OF BREECH LOAD PROBE HEAD


By Arnold Reyenga


experiment done by:


D. Sewell, W


Grimshaw, and A.


Reyenga


atroduction


This experiment was performed in order to measure and plot the radiation intensity


~acroe


the face of the probe head, thereby noticing the points of high intensity and learning


how much radiation is lost because of the beam not striking the foil.


Ezoerimental Setup

The experiment was pet up as shown on the sketches, starting just below the zero


position and moving the probe head up past the 1/8" slot in small steps.


The probe was


set at 81" radius during the bombardment.

Results

The results shown by the graph indicate a high intensity point (21 mr/hr) on the top

outside edge of the copper foil holder, another high intensity point (18.5 mr/hr) on the foil


st above the


medan


plane, and another high intensity peak (13 mr/hr) on the lower out-


side edge at the copper foil holder.
