[Isotope-prod] My talk in Quebec

[George Kharashvili]

Both LEAF at Argonne and Idaho Accelerator Center use Zn-68(gamma,p)Cu-67, the National Isotope Development Center only lists the BNL source, which also uses Zn-68 target, but with proton spallation. There is also a Texas company USradiopharma that lists Cu-67 production by Zn-70(p,alpha)Cu-67, but, as far as we know, they are not producing any. 

LEAF: 
Started production of 100 mCi batches this year. Could increase it to up to 2 Ci per week, but we should keep in mind that it could only be produced periodically as they use the same machine for other work as well. I could not obtain anything like a product fact-sheet, I assume it is similar to the Idaho one below. Argonne does not sell it like BNL. My understanding is that one would need to be in some collaboration with them in order to obtain Cu-67 and in each case the product may have different SA, purity, etc. 

Idaho Accelerator Center: 
Specific Actvity (mass): >10,000 mCi/mg, typically > 20,000 mCi/mg Actvity: 2-100 mCi (delivered) 
Available: Weekly 
Shipment: Shipped dry chloride form 
Packaging: 2ml plastic v-bottom vial, crimp top 
Not intended for human use 

BNL: 
Form 	Copper (II) in 0.1-1.0 M HCl 
Activity 	2-12 mCi/ug (specific activity) 
>10-20 mCi/mL (concentration), or as 
specified by user 
Radiopurity 	>99% (exclusive of Cu-64); the Cu-64 content is ~60% upon delivery (48 hours 
past EOB) 
PRODUCTION 
Source 	Spallation by protons on zinc-68 metal target 
Processing 	Dissolution, electrochemical deposition, and ion-exchange 
DISTRIBUTION 
Shipment 	Crimp-seal bottle 
Availability 	Regular production 
Unit of Sale 	Millicuries

Do we know anything about the (gamma, n) production approach that Argonne is using in terms of production rates, isotopic contamination, purity, etc? Their linac is 1/4 as powerful as LERF and low energy.

Everyone 

I will be presenting a talk by our collaboration at the conference on Accelerator Applications next week in Quebec (AccApp’17). I have taken the talk which was presented this week by George Kharashvili to our Science and Technology Review and added a couple of slides on LERF and using the Energy Recovery mode. I also added Argonne as a supplier of Cu67. 

I would welcome any comments you may have. 

Thanks (and a big thanks to George K for doing all the work) 

Andrew
