Description
The CANadian Rare isotope facility with Electron Beam
ion source (CANREB) is an important component of the
Advanced Rare IsotopE Laboratory (ARIEL) at TRIUMF.
CANREB will deliver highly charged radioactive ion (HCI)
beams for post-acceleration to nuclear physics experiments.
Ion beams injected into CANREB are bunched using a ra-
diofrequency quadrupole (RQB) cooler-buncher and energy
adjusted using a pulsed drift tube for injection into an elec-
tron beam ion source (EBIS) charge state breeder. Charge
breeding occurs by collisions with an electron beam (up
to 15 keV, 500 mA) produced by an electron gun. During
EBIS commissioning, the electron gun became unstable at
currents above 40 mA, with a large fraction of the beam
intercepted by the anode. To address this issue, an electron
gun with an updated design is planned to be fabricated and
installed in CANREB. In order to characterise the new elec-
tron gun, a test-stand will be built allowing for systematic
testing. This paper describes a full simulation model of the
test-stand using FEA software TRAK.
