* Vitaly asked about beam pipe inside PS magnet - will be 6.35 cm OD x 6.03cm ID 316 stainless steel
* Determined 6cm ID tube from collimator wall to target - wall thickness will be 1.5 to 2 mm, ok
+
* Discussion about magnet effects of beam tube - 3166 SS has a permeability of around 1.2 so should have no significant forces.

* Need to look at magnetic affects of adjacent PS magnet

* We will be using the same target cart as the existing Gluex hydrogen target
* Mikhail present latest Flux monitor design
+
* Flux monitor detectors are just upstream and downstream of MRI
** Need to remove PS shield wall
+
* Keith showed best guess at MRI dimensions
** Look at fitting an MRI magnet on platform (5.5 tonnes)
+
** Center of MRI is 15cm above beamline. Beamline is 30 cm above lower edge of MRI bore.
** Need to determine height to center of magnet
+
** Platform rated for over 7 tonnes
** Will it fit on existing platform and is it strong enough?
+
** Keith found additional documentation on field map and power/cooling requirements
** Need to determine power requirements
+
* Vitaly has FLUKA working with magnetic fields and will look at CPS copper energy absorption
 
+
* Tim still needs to run heat numbers from Vitaly for the berylium and tungsten to verify cooling system
** Mikhail to send data sheet for magnet
+
* Existing solenoid will be powered for the experiment

* Vitaly added the following after the meeting
+
**1.  I've imported the Source Model  (FLUKA) that I received from Hovanes.
+
**2. For the moment it runs only without a magnetic field.
+
**3. FLUKA complaints that it can not open the file "cps_mag00.txt"
+
**4. This file is missing in *.zip file !

+
Hovanes, could you please get this file from the author of this model?

Agenda

Phase II is the section downstream of the collimator cave shield wall through the liquid target

Requirements and things to finalize

Minutes

  • Briefly discussed minutes from January meeting
  • Vitaly asked about beam pipe inside PS magnet - will be 6.35 cm OD x 6.03cm ID 316 stainless steel
  • Discussion about magnet effects of beam tube - 3166 SS has a permeability of around 1.2 so should have no significant forces.
  • Need to look at magnetic affects of adjacent PS magnet
  • We will be using the same target cart as the existing Gluex hydrogen target
  • Flux monitor detectors are just upstream and downstream of MRI
  • Keith showed best guess at MRI dimensions
    • Center of MRI is 15cm above beamline. Beamline is 30 cm above lower edge of MRI bore.
    • Platform rated for over 7 tonnes
    • Keith found additional documentation on field map and power/cooling requirements
  • Vitaly has FLUKA working with magnetic fields and will look at CPS copper energy absorption
