Classification: Range Compensator
Maker: Elliot Hammerman

Dimensions:
20.1 x 20.1 x 7.2 cm (7 15/16 x 7 15/16 x 2 13/16 in.)
Description:
The plastic range compensator is drilled out in places in order to alter the extant of depth that the proton beam would penetrate the patient's tumor.
Metal rods are positioned in the face of the range compensator in order to mate it with the brass aperture (2002-1-0030a).
In red ink, "PAA / WED 12/12" is written on the top face and "PAA / WED 12-12" is written on the side. In green ink, "JMC 12/31/1" is written on the top face. A green circular sticker is scotch-taped to the side with the label "12/21/01 / AP."
