NSCL Overview

• Research and operation funded by the NSF under a cooperative agreement

• Coupled K500 and K1200 cyclotrons (up to 175 MeV/u) + A1900 fragment separator to produce beams of rare isotopes

• Rare isotope stopped and studied in a stopped-beam area

• Reaccelerated beams in ReA3 to 3-6 MeV/u (ReA6 under construction; beams 6-12 MeV/u)


NSCL Operational Overview


>1000 RIBs produced > 911 RIBs used in experiments> 87 RIBs stopped

(of 23 different chemical elements)

• The NSCL is presently funded to run about 4000 hours/year. Goal is to have 90% availability and run within one day of schedule [ISO-9001 registered QMS]

• FY20 we will run 5,055 hours; CCF availability has been 80%; ReA3 availability has been 98%

• Beams delivered for experiments at NSCL:

NSCL Outreach


NSCL offers a broad spectrum of outreach activities that target the public and students of all ages. Faculty Outreach Advisor: Artemis Spyrou• More than 10,000 Lab-public

interactions per year• New exhibit SMASH opened at

Impression 5 in Lansing (100,000 visitors per year)

• Outreach committee with representation from faculty, research associates and graduate students

• Outreach Coordinator: Zach Constan(MSU-funded position)

• Web Content & Graphic Designer: Erin O’Donnell

• PAN and NSSS offered online this year

NSCL Diversity Efforts


NSCL is committed to fostering a diverse scientific workforce. Diversity Committee (Chair, Andreas Stolz)• Laboratory Diversity Plan based on continual

improvement principles• Laboratory Code of Conduct – goal to foster a supportive

environment https://www.nscl.msu.edu/about/code.html• Use of best practices in hiring – training, effort to search

for a broad pool of applicants• Participation in recruitment programs, e.g., PING• “Greensheet” series on women and minority scientists• Cultural awareness slides – based on lab experiences• Women and Minorities Lecture Series; most recent Paul

Gueye (see NSCL website for the recorded talk)• Are working on implementing a cultural awareness

program• Climate survey, improved student and postdoc surveys• AIP TEAM-UP self assessment survey done by all faculty

https://www.nscl.msu.edu/about/code.html


NSCL COVID-19 Status and Schedule• NSCL was significantly impacted by the COVID-19 pandemic

– We were shut down from 23 March to 8 June for ReA3 and to 20 June for the CCF (We lost approximately 3 months of CCF operation)

– Lab safeguards are in place to prevent the transmission of COVID-19 (strict 6 ft separation, face coverings, twice per 8-hour shift cleaning, no sharing of tools, temperature screening on entry, …)

– Prior to entry, outside users must be tested for COVID-19 and follow specified rules• NSCL will shut down in November to accommodate the FRIB construction

schedule – We will not be able to complete all approved CCF experiments – Priority was given to student, postdoc, junior faculty and staff projects. Equal

distribution of beam time between the various groups was also a factor• ReA3 and ReA6 will start an NSF-supported stand-alone user program in after

CCF is off (ReA PAC was held in March 2020)• NSCL ends 30 September, 2021

NSCL Leadership and Leadership Changes

• NSCL is part of the FRIB Laboratory at MSU. – FRIB Laboratory Director, Thomas Glasmacher– NSCL Director, Brad Sherrill

• NSCL Leadership Team (two changes this year)– Alexandra Gade (NSCL Chief Scientist) – Richard Jacobson (Executive Director) – David Morrissey* (AD for Operations) – Hiro Iwasaki (AD for Education) – Sean Liddick (AD for Experimental Research)– Jie Wei (Accelerator Physics Head)– Dean Lee* (Theory Head, separately funded) – Hendrik Schatz (JINA-CEE Director, separately funded NSF Frontier

Center)– Georg Bollen (Applied Isotope Head)

• * On 1 September Andreas Stolz will become the AD for Operations until the CCF shuts down at which time Antonio Villari will oversee operations


NSCL User Community


• FRIB Users Organization (FRIBUO) represents the NSCL users• Present membership is 1,563 people (118 US Colleges and

universities, 38 States, 236 International institutions, 63 countries)

• Publications based on NSCL experiments in CY19:18 Letter/Letter-like publications (Nature, PRL, PLB, PRC-R)110 Including all journals (PRC, NPA, NIM, etc.)

Third NSCL GRETINA campaign will conclude in one week → Move to ANL


• 24+24 experiments were run successfully during the previous two GRETINA campaigns at NSCL. The third campaign comprises 14 experiments

• A broad range of topics was addressed during NSCL III, including the study of shell evolution, collectivity in rare isotopes, weak interaction strength, and isomer spectroscopy

• 50 papers so far out of NSCL I – III with several more papers submitted and many more in preparation (http://gretina.lbl.gov/publications)

• 13 PhD theses completed with many more in progress• F

NSCL Facility Developments

• Infrastructure Improvements – Installation of Cyclotron-Stopper in N2/N3 complete– SECAR installation and commissioning continues– Refurbishment of ReA3 RFQ completed successfully– High current EBIT from BNL being tested (A. Lapierre, A. Villari)– ReA6 on schedule for early 2021 start– Batch mode ion source design underway

• NSF-supported MRI Projects– ACGS next generation beam thermalization device, operational– He-jet on-line harvesting system (successful test, update underway to allow first

experiments)– Optical Ion Chamber under design

• Other Projects– Isotope harvesting from prototype beam stop (G. Severin, 47Sc generator

produced)– Solid stopper test (J. Shusterman, Hunter College)

ReA3 Accelerator

Rare isotopes from the CCF/A1900 are stopped in N4 are charge-bred and reaccelerated

Experiments often consist of two or three stages: a) Setup equipment with stable beam (close to RIB)b) Run experiment with reaccelerated RIB from CCFc) Run reference if contaminant observed in expt.
