Overview R&D for pBar Target Diagnostics

This page summarises test measurements intended for the pBar target.

MEASUREMENTS AT EXTERNAL FACILITIES

HIT Measurements with Proton Beams

Type of investigations:

LEBT: Measurements with SEM grids
MEBT: Measurements with SEM grids
HEBT: Measurements with P43 screen, MWPC and IC to estimate lower detection limits
HEBT: Measurement of MWPC gas gain

Beam conditions:

Date : February 2011
Beam : Protons
Energy: 48 or 220 MeV
Beam lines: LEBT, MEBT, H1-H3

Summary of HIT measurements

MEASUREMENTS AT GSI

HTP Measurement with CERN BLMS

Date : June 2010 and April 2011 Beam : Uranium, Argon, Carbon Beam line: HTP, in front of dump

ToDo:

Build DAQ for fast extraction
Measurement with fast extraction
Measurement with slow extraction (dedicated shift!): light, medium and heavy ions

HTP Measurement with SEM as air ionisation chamber

Date : November 2010 Beam : Uranium

ToDo:

Measurement with pulsed high voltage (signal of SEM emission in air without ionisation component)
Build segmented SEM for profile measurements
Measurements with fast and slow extraction
