Superconducting RFQs (SRFQs), the first SC RFQs ever made operational for users, have been operated on the PIAVE SC heavy ion linac injector at INFN-Legnaro since 2006. The structure is split into two resonators and is limited to the accelerating RFQ sections. [...]

Pushing the intensity envelope at the ATLAS linac
/ Mustapha, Brahim (Argonne) ; Dickerson, Clayton (Argonne) ; Hendricks, Matthew (Argonne) ; Ostroumov, Peter (Argonne) ; Pardo, Richard (Argonne) ; Scott, Robert (Argonne) ; Zinkann, Gary (Argonne)
The ATLAS linac at Argonne National Laboratory has recently been upgraded for higher beam intensity and transport efficiency. Following the installation of the new RFQ, we have performed a high-intensity run using a 40Ar⁸⁺ beam. [...]

The ATLAS Intensity upgrade: Project overview and online operating experience
/ Pardo, Richard (Argonne) ; Barcikowski, Albert (Argonne) ; Conway, Zachary (Argonne) ; Dickerson, Clayton (Argonne) ; Hendricks, Matthew (Argonne) ; Kelly, Michael (Argonne) ; Kim, Sang-Hoon (Argonne) ; Luo, Yong (Argonne) ; MacDonald, Stephen (Argonne) ; Mustapha, Brahim (Argonne) et al.
ATLAS, the world's first accelerator to use RF superconductivity for ion acceleration, has undergone a major facility upgrade with the goals of significantly increased stable-beam current for experiments and improved transmission for all beams. The dominant components of the upgrade are a) new CW-RFQ to replace the first three low β resonators, b) a new cryostat of seven β=0.077 quarter-wave resonators demonstrating world-record accelerating fields, c) an improved cryogenics system, and d) the retirement of the original tandem injector.

A fast, compact particle detector for tuning radioactive beams at ATLAS
/ Dickerson, Clayton (Argonne) ; Deibel, Catherine (LSU, Baton Rouge (main)) ; DiGiovine, Brad (Argonne) ; Hoffman, Calem (Argonne ; ANL, APS) ; Lai, Jianping (LSU, Baton Rouge (main)) ; Lin, Ling-Ying (Argonne) ; Pardo, Richard (Argonne) ; Rehm, Ernst (Argonne ; Argonne, PHY ; Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Santiago-Gonzalez, Daniel (LSU, Baton Rouge (main) ; Argonne (main) ; Louisiana State U.) ; Savard, Guy (Argonne ; Argonne, PHY ; Chicago U.)
Radioactive ion beams (RIB) at the Argonne Tandem Linear Accelerator System (ATLAS) are produced either from the in-flight method at 5-15 MeV/u for A < 30, or via reacceleration of fission fragments from the CAlifornium Rare Isotope Breeder Upgrade (CARIBU) at 4-10 MeV/u for 80 < A < 160. These RIB are typically accompanied by contaminant beams >100x more intense. [...]

Upgrade of the ATLAS Positive Ion Injector Bunching System
/ Sharamentov, Sergey I ; Bogaty, John ; Clifft, Benn ; Pardo, Richard C
Over the last few years, significant efforts were concentrated on improving the ATLAS Positive Ion Injector (PII) RF bunching system, consisting of a four-harmonic pre-buncher, Traveling Wave Chopper (TWC) and a single-frequency sinusoidal re-buncher. The primary goal was to improve RF field stability with a redesigned RF system and to improve buncher performance for higher current beams resulting in better bunch stability and time structure at the first PII superconducting resonator.

Progress with the 2Q-LEBT Facility for the RIA Project
/ Vinogradov, Nikolai ; Aseev, Vladislav N ; Kern, Michael R L ; Ostroumov, Peter ; Pardo, Richard C ; Scott, Robert
The Rare Isotope Accelerator (RIA) facility utilizes the concept of simultaneous acceleration of two charge states from the ion source. We are building a prototype two charge-state (2Q) injector of the RIA Driver Linac, which includes an ECR ion source originally built by Berkeley Ion Equipment Corporation, a LEBT and one-segment of the prototype RFQ.

Radioactive Beams from 252CF Fission Using a Gas Catcher and an ECR Charge Breeder at ATLAS
/ Pardo, Richard C ; Baker, Samuel I ; Hecht, Adam ; Moore, Eugene F ; Savard, Guy
An upgrade to the radioactive beam capability of the ATLAS facility has been proposed using 252Cf fission fragments thermalized and collected into a low-energy particle beam using a helium gas catcher. In order to reaccelerate these beams an existing ATLAS ECR ion source will be reconfigured as a charge breeder source. [...]
