CNAO @ Feb 2012

Aim

• Target? PMMA
• Particle rates? Up to GHz. We are going to need ~ 1 MHz. Seems to be feasible: degrader can be added and we are also building a collimator.

Beam Energy: need of a too long PMMA ... now we have 10-22 cm... Beam Spot 0.9 -- 1.1 cm...

TPS that have to be prepared.

1. STILL a DRAFT
2. First night: Take 1 PMMA cylinder and I see what happens varying the angle.Publish fluxes of protons from PMMA. I want to give 1 Gy (treatment like).

1. We are going to redo Catania: different energies and different angles.

When? [Draft for time plan]

Februrary 9 -12 ... For 2 nights.... (16 hours).

• Thursday (9/2) we star, but friday morning we go back to stealth [patient being treated]: during the night we try to calibrate everything!
  1. With Radioactive sources we calibrate LYSOs and NAIs, with beam (if possible) we calibrate the Beam Monitor
• Friday we install everything on the final geometry.
• Saturday and Sunday we take data

• Detectors should be already calibrated, we measure a reference point on the final setup on thursday night.
• Thursday night we need (beam) time to
  1. Acquire t0s for BM
  2. check that ST relations are fine
  3. Calibrate NaI?
  4. Calibrate LYSO?

Where?

Hall 1. Control room 3m out of corridoio (needed to check cables lenght).

• Long Cables can exit from experimental hall: to be checked as a function of cable thickness.
• There are several IN<->OUT from hall to control room: a complete list of signals that we want outside should be made and Xcheked with available connections

GAS

Ar/CO2

• We need to bring the premixed bottle
• Exhaust is ok.

Mechanics

• Rec for electronics? Arrived/mounted... We will bring it.
• Needs to finalize the choice for the mechanical structure (we need to check how it goes with the angles study)

1. Lyso + collim
2. Two Nai at 180 degrees
3. New Beam Monitor

Hardware

• New Beam monitor
• 2 NaI detectors.
• Collimator (slit)
• 2 LYSO
• Start Counter [we already have it]
• Palettino before New Beam Monitor?

DAQ

Checked that we can bring our WS1 for daq. There will be an ethernet connection from control room to hall: private network to connect to the WS1, and then we have a wireless to connect to outside. We will use a bridge for the acquisition (either usb or fiber).

signals we would like to acquire

• 36 tdc times from beam monitor
• tdc and adc for the NaIs
• Signals from machine?
• RF or monitoring of position/energy
