Significant Planning Assumptions: Scope

Hardware ABS Injection Volume Purifier Interconnections (ABS Interface, Plumbing to Cells) Fluid Control (Valves, Pressurizer, Volume Displacement)

Tests Injection Purification Pressurization Full System

Installation at ORNL McClintock Purifier

Cell Isolation Valve (V1) Body/Stem/Seat is NOT part of He3S

Significant Planning Assumptions:Technical

Technical Assumptions Minimal adaptation of ABS Evaporation purification Two Purifiers Volume Displacement System Pressurization of cell to 1 atm Diffusive 3He flow 0 pumps. 1 V1 valve/cell All actuators use “Heliomatic” mechanism for 300 K to 4 K A certain model for interconnection

EDM


Other Significant Planning Assumptions:

Procurement Hardware is ordered from vendors (build to drawing). Local technical support at collaborating institutions not used. It’s

hard to estimate without a firm design. This is wrong but…

Manpower Engineering by Bartoszek Engineering (more later) Work package leaders assumed, but not all confirmed Local technical support used for installation and testing.

Testing All systems must be successfully tested before arrival at ORNL Tests take place in parallel at different locations.

Interfaces

DAQ Slow controls

Cryostat/Cryogenic Services Mechanical support Instrumentation and motion feed-through 50 K, 4 K, 0.3 K thermal links

Coils and Magnetic shielding Upper cryostat cos() holding field Over-all magnetic model

Measurement Cell Insert Interface to V1 valve body/stem Plumbing connections into inner volume

He3S Interfaces With MANY Subsystems

EDM


Technical Scope Definition Issues

Resolution of many technical issues could totally change the scope (see Technical Assumptions). Example: If evaporation purification found to not be practical

purifier work package would be completely different.

Important materials issue: 3He Friendliness (more info needed – not just for dTPB, but teflon, nylon, DryFilm,…

Interfaces! (Where does He3S end?)

EDM


Equipment Performance Issues

Injection polarization (90%)

Injection efficiency (How much 3He enters the LHe?)

Relaxation time in the collection volume (100 s)

Polarized 3He loading time (1000 s)

Quality of purification (1011 3He atoms/cc)

Time required to purify

Regeneration frequency

Valve lifetime (5000 cycles)

Superfluid leak tightness (valves, joints)

3He friendliness of plumbing (pol = 80% at the cell)

Heat load to DR

Staffing Plans/Issues

Key People Needed: Work package leaders need to be confirmed. Possibly new

leaders identified Some additional engineering will be necessary

Identifying in-house technical skills and capabilities may allow less outside work – could save money.

Special skills (e.g. glass blowing) may be required.

EDM


Procurement Planning

The largest single items to be procured are the valve actuators $30k Need 8 for valves and 2 more for bellows. In actuality these may be built of smaller parts purchased

separately:

Warm actuator $2.5k Feed-through from warm to 4K piston and cylinder $5.0k 4K piston and cylinder in upper cryostat $10.0k4K piston and cylinder on 4K shield $10.0kGaseous Hydraulic plumbing between cylinders $2.5kTotal $30.0k

Next largest items are SQUID electronics and pumps (~$20k)
