Title:

Increase of Lifetime of Thallium Zeolite Ion Source for Single-Ended Accelerator

Date of publication:

May 1995

Key words:

ion source, beam probing, plasam diagnostics, thallium, accelerator

Abstract:

Utilizing multiple sintering, we have considerably increased the lifetime of a thallium (TI) zeolite ion source used in single-ended electrostatic accelerators. The obtained lifetime of a small ion source (6.4 mm in diameter and 10 mm long) is about 4400 muAh(70 muAh/mm^3 for TI material).
