Beam Diagnostics for Low Energy Proton Beam

Abstract

An 800 MHz Radio Frequency Quadrupole (RFQ) is being designed for obtaining 2MeV protons at KAHVELab. The beam originating from the ion source has to match the RFQ via an optimised Low Energy Beam Transport (LEBT) line. LEBT line consists of two solenoids, a beam diagnostic box in between, and two steerers. The solenoids will be utilised to focus the divergent beam coming from the microwave discharge ion source to the RFQ.The steerers will be deployed to direct the beam into the RFQ. The diagnostics are aimed to measure the proton beam’s current, profile as well as the beam emittance upstream of the RFQ. The measurement box is designed and ready for production. The prototype for the Faraday cup is produced, for the scintillator screen will be home-built, and for the pepper pot plate is being manufactured. In this talk, the magnetic field measurements of the steerers, the electromagnetic simulation and the assembly of the FC and design code of the emittance measurement will be presented.This study is supported by TUBITAK Project no: 119M774
