[Isotope-prod] Fwd: Experiment in the injector

[Hari Areti]

When the transition occurs is unclear. We should act fast.

Hari, 
This is fine and OPS will support this program if we remain idle at 2K. Once we hear that beam operations are terminated for Spring, we will transition to 4K relatively quickly. 

We cannot generate 18.5 MeV of beam energy without 2K cryogens.

I am going to ask Ops for time at the injector for irradiating Gallium. 

Let is fix a few things and work out the logistics. 

Requisites: 
Do we have enough target material? (PD, GK) 
Do we have BNNT holders? (KJ) 

Beam parameters 

1. Beam Energy 18.5 MeV 
2. Beam current ? 
3. Beam time? 

Logistics 

Test plan ( revive the previous one, if we had one) 
Do we have the means to measure energy and beam size? (I will check) 
Assuming that VCU collaborators have time, how do we ship the 
irradiated sample? 

Anything else? 

Once our thoughts are organized, should we meet (even on the phone) 
for a few minutes to organize the experiment? 

Thanks.
