Upgrading the NSLSUpgrading the NSLS• User science needs higher average brightness and

shorter pulses for “grand challenge” problems• Goals for the Upgrade

• Highest Average Brightness in 5-20 keV energy range10,000-fold increase in average brightness over NSLS X25 beamline

• More Straight Sections~ 21 Insertion Device Straight Sections (Currently only 5 on X-ray)

• Shorter Pulses w/ Higher Peak Brightness~ 30 psec pulse length (FWHM) (Currently 400 psec)

• Highest Average Flux10x increase over current NSLS flux

DOE Planning BackgroundDOE Planning Background• Summer 2002 – Ray Orbach requests that each Associate

Director (AD) of the Office of Science (SC) develop a 20-year plan for facilities using input from Advisory Committees, NRC studies, community workshops, etc

• November 2002 – The five SC ADs present a total of 53 upgrades and new facilities to Ray Orbach

• December 2002 – Ray Orbach charges each Advisory Committee with assessing these plans by March 2003

• December 2002 – A BESAC Subcommittee is formed in response to the charge to BESAC. The Subcommittee is co-chaired by Geri Richmond and Sunil Sinha.

BESAC Recommendation: NSLS Upgrade BESAC Recommendation: NSLS Upgrade

The NSLS is one of the world’s most productive synchrotron facilities. Having led the way for dedicated X-ray sources, it continues to be a world leader in the output of synchrotron-based science with an impressive 650 publications per year. It is critical that the NSLS continue to deliver the highest quality synchrotron radiation and support its scientifically diverse user community, which is predominantly in the northeastern sector of the nation.

To maintain their prodigious scientific output in the near future will require continued beamline innovation and development, and, for instance, instrumentation for higher energy and spatial resolution. These enhancements will best be achieved through increased and sustained AIP support.

BESAC Recommendation: NSLS-IIBESAC Recommendation: NSLS-II

• One of the world’s most scientifically productive x-ray sources with ~ 4000 users.

• Proposed - 3rd generation ring, SC LINAC, HGHG FEL and upgraded VUV ring.

Recognizing the continued need for 3rd

generation x-ray sources, we recommend that NSLS and BES formulate a plan for a 3rd gen. ring.

Superconducting Mini Gap UndulatorsSuperconducting Mini Gap UndulatorsWhy SCU?

• Short-period (~ 1 cm) is a must to generate tunable, multi-keV photons in medium-energy rings

• Higher fields, higher K (>2.2), full tuning range (3:1) attainable only with SC technology

R&D• NSLS pioneered PM MGUs.• NSLS and BNL SC Magnet Division are

setting up a SCU testing facility.• NSLS joined SLAC, ALS & APS in

collaboration in SCU R&D.• Parallel R&D efforts in Europe (ANKA,

ACCEL) may lead to commercial sources of SCUs.

• ⇒ Confidence in availability of SCU in time for NSLS-II
