Agenda and Notes

1. Overview

Cryogenics is moving forward with the design and engineering for a new 2K cold box to replace SC1 using new LCLS2 technology. The design will likely be a cold box with compressors and a separate cold box for the heat exchanger. It will take maximum advantage of the LCLS2 design and drawings.


2. Estimated Costs

$2.4M (actual) LCLS2 1 Set of 6 cold compressors, mag bearings, frequency drives

$0.9M (actual)LCLS2 1 Set of 6 spare cartridges cold compressors, mag bearings, frequency drives

$2.5M (estimated)LCLS2 Compressor cold box

$1.0M (estimated) LCLS2 2K/4K Heat exchanger and cold box

$0.2M (estimated) Control system and electrical power

$1.0M (estimated) Installation and integration

Total $8.0M


Action Items

1. SC1 replacement cold box engineering and design manpower plan

2. Hasan will determine how close the pressure/flows match up between LCLS2 and JLAB.

3. Do we need 6 drives or 5?

4. Where can it be installed without permanently mating it to one particular 4K cold box?
