We divide the diagnostics in two main categories:commissioning and day-to-day operation.
The first will be used to find the right settings of the machine and to study the beam quality and machine performance.
The second will be used to survey the machine and for fine tuning.

Commissioning
DTL tank 1, 2, 3:movable diagnostics bench (MB):transmission, transverse and longitudinal emittance, energy and energy spread, set rf phase and voltage.moving slit device (transv. emittance)energy degrader (set phase)Faraday cuptime-of-flight energy measurementbunch length measurement (Feschenko monitor)CCDTL, SCL:setting-up using the permanently installed diagnostics full commissioning (only at high energy): transport the beam to a permanently installed measurement line at the exit of the linac (depending on installation schedule)energy: spectrometer dipole in the ML and time-of-flight (phase pu) in the linacbunch length measurement (Feschenko monitor)
K.Hanke / TDR Meeting / 13 June 2006
Operation
source/LEBT/RFQ/chopper line:intensity: retractable Faraday cup and beam current transformer. profile: SEM grid.
RFQ and chopper line:intensity: two beam current transformers permanently installed upstream and downstream of the chopper.position/phase/intensity: 3 pick-ups
K.Hanke / TDR Meeting / 13 June 2006
Operation
DTL, CCDTL, SCL:position/phase/intensity: after each tank of the DTL, after each of the 8 modules of the CCDTL and after each of the 4 modules of the SCL.combined position and phase pu, which measures also the beam current within 5%.beam loss (interlock!): BLMs along the linac and transfer line. beam current: in addition “real” beam current transformers after DTL, CCDTL, SCL and in the transfer line (HEBT). beam profile (SEM grids): after tank 3 of the DTL, after modules 4 and 8 of the CCDTL and after modules 2 and 4 of the SCL.
