====== 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 

\\

===== 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
