THE ARGONNE TARGET LIBRARY

As part of the proposal to DOE-NP for the Center for Accelerator Target Science (CATS) initiative, one of the objectives was to develop an inventory of existing targets that will serve as a pool available to the community. Targets collections have been recovered from Yale University due to the closing of their Tandem Accelerator Facility. In addition, accumulated targets from target preparation in the Physics Division over several decades have also been assembled with the intent of providing them to whomever would have a use for them. Space has now become available to compile, catalogue and house these collections. Thus, the Argonne Target Library has been established and its progress and outlook will be discussed in detail.


INTRODUCTION AND MOTIVATION
 During the course of ATLAS target preparationmany targets are produced.
-at first as "practice" depositions employing stable materials when using isotopeas many targets as possible are made  These targets naturally accumulateplus targets brought here.
perhaps to be used again in future experiments loathe to throw any targets away (especially isotope!)  Many target laboratories therefore have large supplies of "unused" targets -30 years ago -Thomas remarked "why don't we have a listing and make these targets available?" -during the '90's Folger @ GSI built an indexing target storage system  On a very small scale some of these targets have been made available former ANL colleagues (and others) have periodically been provided targets and we entertain making new targets (on a case-by-case basis)

INTRODUCTION AND MOTIVATION
 Due to budget cuts many Accelerator Facilities have ceased operations.
-forcing some former "target labs" to also shut down responsible folks have realized the value keeping their target collections  Labs with AND without target making capabilities have benefitted.
from obtaining these targets for re-use but, for the most part, these collections are generally unknown  This has recently been discovered in the case of the WNSL Tandem closing.
the Yale target lab was cleaned out and many targets recovered several collections of targets were also obtained (for re-use?)  One objective of the CATS Proposal would be to collect such targets.
develop an inventory of these target collections make them available as a pool to the low-energy community "In Addition …" Brookhaven targets recovered from WNSL

INTRODUCTION AND MOTIVATION
 Three days (Dec. 2013) were spent at WNSL (Yale U.) to organize the target facilities and recover whatever targets might be worth saving.  Many of these targets originated in the PHY Division Target Lab!

The Closing of the Yale Tandem
Organized into targets worth saving.
Returned to ANL Physics Div. targets returned to ANL

INTRODUCTION AND MOTIVATION
 In addition, at Yale, there were ALREADY collections of targets from both Brookhaven (BNL) as well as Los Alamos (LANL).  These were carefully packed and shipped to ANL.

Arrival of targets at ANL

INTRODUCTION AND MOTIVATION
 Three decades of target production in support of ATLAS experiments have accumulated into a formidable inventory and currently reside in M-057 storage.
 In addition, a large collection of stable "practice" target preparations also exists in the Target Lab R-150, along with targets we intend to keep in "circulation."  We plan to use the Yale collections as a learning "Test Bed" for the cataloging and handling of this large target inventory.

Finish Cataloging the Collections
Argonne targets still needed to be organized and compiled  LIBRARY RULES -Proposed… i) individual target requests will be limited to one specified target and up to two targets shipped if possible -(one for a spare).
ii) priority will be assigned to domestic requests and of those, being DOE (& NSF) investigators will be addressed first. iii) wherever possible a user supplied FedEx account will be needed for shipping. iv) a vacuum target transport container may be necessary (such as those marketed by MicroFoils, Inc.)-it should be supplied in advance by the requestor. v) any future approved rules employed as they arise. -Visitors • Controlled access?
