MOU and BAT Charter


Main Elements of BAT Charter

• Beamline Advisory Team (BAT) is a small group of scientists who submit a Letter of Interest (LOI) to NSLS-II, representing a particular community, to propose a specific beamline based on a specific set of experimental techniques to carry out a particular scientific mission.

• Submitted LOIs are reviewed by external reviewers and by the NSLS-II Experimental Facilities Advisory Committee (EFAC), and approved by the NSLS-II.

• Primary role of BAT is to advise the NSLS-II Experimental Facilities Division Director on the scientific mission and the technical requirements for the beamline and to work closely with the beamline scientists during design, construction, and commissioning of the beamline.

• NSLS-II has the overall responsibility for the design and construction of the beamline, including hiring of staff. Major beamline revisions are to be made in consultation with the associated BAT and the community at large. Final decisions on any issues in the design and construction of a beamline reside with the NSLS-II.


Need EFAC Advice on the Following …

• Does the BAT Charter adequately describe roles and responsibilities of the BAT?

• Does individual BAT membership adequately represent the particular user community for the beamline?

• To ensure high quality interactions between BAT and NSLS-II, we believe there is a need for formal communication channels between EFAC and the BATs:• to periodically review how BAT is doing by EFAC, e.g. every 1-2 years;• to allow BAT to register concerns and complaints about certain NSLS-II actions.

• Should NSLS-II have a BAT Council, consisting of representatives from all BATs?

Project Beamline Conceptual Designs

• Finalizing X-ray optics and beamline layout;• Optimizing insertion device specifications; • Heat load analysis on x-ray mirrors and

monochromators; • Concept of end-station instrument;• Iterating with BAT;• Cost and schedule update


Project Beamline Insertion Device Optimizations

• Studies on insertion device options: Oleg Chubar (XFD/ASD) Toshi Tanabe (ASD)

• New XFD/ASD joint working group on IDs: members include XFD, ASD, and NSLS staff; meets weekly to discuss ID options and specifications; current focus is on high-beta long straights.

Project Beamline Heat Load Analysis

• Thermal analysis on x-ray monochromators

Water-cooled Si mono.Max. slope error ~ 20 rad

LN2-cooled Si mono.Max. slope error ~ 0.2 rad

Vishy Ravindranath, Sushil Sharma (ASD) Lonny Berman (NSLS)

• Heat load analysis on x-ray optics are on-going for six beamlines• Primary conclusion is that LN2-cooled Si mono is needed for hard

x-ray undulator beamlines; Systematic study is underway.


Hard X-ray Nanoprobe in Satellite Building

• Vibration isolation from main building• 100 m long larger working distance• Concrete expt. hutch w/ acoustic damping• Consideration of vibration isolation

similar to EM, from ground up • Air-lock entry and

temperature stability

Laboratory Office Building (LOB)

• XFD effort on LOB programming requirements:• Held several expanded staff meetings to

discuss LOB space requirements• Did detailed estimates on staffing levels and

expected number of users, & their office needs• Did detailed analysis on basic equipment needs

that are required by most user groups in support of their experiments at beamlines• Worked with professional lab planners from HDR on realistic laboratory layouts• Held a town-hall meeting with broader community to discuss with the community

about our current plan and invite feedback

• LOB design at CD-2 was baselined under certain financial constraints, and needs to be reevaluated.

• Expanded LOB design has been given the green light by DOE to proceed.


Outreach to Community

• Six beamline advisory teams, with combined membership of >50 scientists representing a diverse user community, have been the main focus of community interactions during the past year.

• NSLS-II XFD participations in several community organized workshops and meetings, including:

• BER/NIH workshop on life science at NSLS-II, Sep.11-12, 2008• High pressure research workshop, Oct. 6, 2008• XAS community workshop, Mar. 6, 2009• Workshop on SR applications in microelectronics, Mar. 20, 2009• Workshop on SR applications in glass research, Apr. 6, 2009• Weekly beamline transition workgroup meetings

• Focused efforts in XFD on defining BATs, recruitment, R&D infrastructure, and beamline conceptual designs have made it difficult to be more engaged with the community during the past year.

• With more staff scientists on board, we fully expect that community outreach will regain momentum in the coming year.

Responses to Previous EFAC Recommendations


Issues and Outlook

• High resolution R&D programs, 1 nm and 0.1 meV, are very challenging; Outcomes may have impact on beamline designs

Need to design beamlines with built-in flexibility to accommodate R&D outcomes

• Interface activities with ASD especially in the area of insertion device optimization and front-end designs; may impact beamline schedule

Need proactive interface management and considerable interactions at several levels

• Recruiting and retaining best staff in XFD Hiring of in the coming months will focus on nanopositioning eng., optical metrology

expert, and beamline scientists. Efforts to create and maintain a nurturing research environment in XFD and

encourage discussions on science, R&D, and career developments.

• Managing priorities and interacting with BATs Need open and transparent discussions with BAT so difficult decisions can be made

with BAT inputs; EFAC input and advisory are welcome.


Summary

• NSLS-II Experimental Facilities Division is making good progress in staff recruitment, infrastructure building, x-ray optics R&D, and beamline conceptual designs.

• Beamline Advisory Team selection process for project beamlines completed by CD-3. Beamline advisory team charter developed.

• Beamline conceptual designs, with full engagement of BATs, are well underway and on schedule.

• Considerable interactions with community and NSLS are on going, particularly in LOB programming and workshop participations. An increasing level of NSLS-II outreach activities are anticipated for the coming year, given much higher level of staffing in XFD.

• We appreciate EFAC input and advice on many topics discussed or to be discussed at today’s meeting
