Use of a Streamer Chamber for Low Energy Nuclear Physics

A small streamer chamber has been implemented for low energy heavy ion reaction studies at the LBL 88" cyclotron. The response of the chamber to light and heavy ions below 35 MeV/nucleon has been examined. The limited sensitivity of light output as a function of ionization works to advantage in recording a wide variety of tracks in the same photograph whose energy loss may vary considerably. Furthermore, as gas targets are attractive for several reasons, we have investigated the suitability of Ar and Xe for use in streamer chambers.
