BNL 48724 Informal Report NATIONAL SYNCHROTRON LIGHT SOURCE USER'S MANUAL: GUIDE TO THE VUV AND X-RAY BEAMLINES Fifth Edition Edited by: Nicholas F.

FOREWORD The success of the National Synchrotron Light Source is based, in large part, on the size of the user community and the diversity of the scientific and technical disciplines represented by these users. As evidence of this success, the VUV Ring has just celebrated its 10th anniversary and the X-ray Ring will do the same in 1995. In order to enhance this success, the NSLS User's Manual: Guide to the VUV and X-Ray Beam lines - Fifth Edition, is being published. This Manual presents to Ihc scientific community-at-large the current and projected architeclure, capabilities and research programs of the various VUV and X-ray beamlincs. Also detailed is the research and computer equipment a General User can expect to find and use at each bcamline when working at the NSLS. The Manual is updated periodically in order to keep pace with the constant changes on these beamlincs. The editor wishes to thank the numerous PRT, IDT and NSLS personnel whose efforts have made this Manual possible. Companion documents, the NSLS Experimenter's Handbook and the NSLS Community Directory, are also available through the User Administration Office (516-282-4703). -ill- Table of Contents Foreword iii Section A.

In addition: Section B (VUV) consists of a listing of VUV storage ring parameters in Table 4, a summary of all VUV beamline energy ranges in Figure 5, and descriptions of the individual VUV beamlines U1A through U16B; Section C (X-Ray) consists of a listing of X-Ray storage ring parameters in Table 5, a summary of all X-Ray beamline energy ranges in Figure 6, and descriptions of the individual X-Ray beamlines XIA through X26C. The reader will note that all of the beamline descriptions in Sections B (VUV) and C (X-Ray) are dated. The reason is that beamline configurations are constantly changing. Potential users should not necessarily assume that the beamline in which they are interested corresponds exactly to the description given in this manual. They should contact the beamline Spokespersons or Local Contacls for further in-depth information. Individuals wishing to submit research proposals to the NSLS should contact: User Administration Office National Synchrotron Light Source Building 725B, Room 2-100 Brookhaven National Laboratory Upton, NY 11973 USA Tel: (516)282-4703 FAX: (516)282-7206 A Word on the Writing of Beamline Descriptions Great care is exercised to ensure the accuracy and the up-to-date nature of the information presented in each of the beamline descriptions. The writing of the descriptions is a strongly collabora- tive effort between the editor, Nicholas Gmiir, and the Spokesperson or Local Contact of each PRTADT. Emphasis is placed on succinctness as well as on uniformity of presentation and terminol- ogy. Also encouraged is the need to demonstrate the unique qualities of each beamline. Signed and dated approval by the PRT/IDT is required for inclusion of each beamline description in this User Manual. -Intro/3- BKAMLINK EQUIPMENT UTILIZATION FOR GENERAL USERS as excerpted from the NSLS Policies and Procedures Document - Volume I, September 1988. PR 1711)1 Equipment Availability to General Users The capitalization strategy for the NSLS, i.e., the PRT/IDT system, is being carried over into operations of the facility. Every beamline made available to the General User must be capable of performing the generic class of experiments for which it was approved by the Program Advisory Commit- tee (PAC). Unless the government funding agencies and industrial laboratories arc to provide duplicate or multiple end stations for each beamline, a significant investment, the equipment provided to the PRT/IDTs must be made available to the widest possible community. PRT/IDTs must, however, be allowed to exclude equipment from general use when its function can be compromised or when the equipment itself is the embodiment of the science of the PRT/IDT member. The NSLS must provide a mechanism to protect innovation and scientific uniqueness of equipment by providing those who invest in technically innovative apparatus the exclusive use of such equipment for some period. General User Technical Support The PRT/IDT system as operating at the NSLS dictates that technical support for General Users who arc performing experiments at a PRT/IDT beamlinc be provided by the PRT/IDT. It is beyond the resources of the facility to provide technical support for non-facility beamlines. However, it is also beyond the resources of the PRT/IDTs to provide technical support to the General User at a level above that provided to members of the PRT/IDT. The General User must be informed that: 1. The beamlinc staff must support the General User community for the percentage of time agreed to by the PRT/IDT staff and the NSLS. 2. Beamlinc personnel arc not obliged to staff the bcamline beyond the level normally available to PRT/IDT members. 3. General Users must arrange lo have their personnel trained and certified on a particular beamline. 4. It is the responsibility of the beamlinc staff to conduct such training. 5. The schedule and type of training is at the discretion of the beamline personnel. 6. Approval for a General User to operate a beamline without beamline personnel present is the decision of the bcamline representatives. 7. The beamline personnel can refuse continued training to General Users who fail to become certified. IMPORTANT The individual beamlinc Experimental Apparatus and Computer System Hardware and Software sections contained in this document reflect what is available to General Users. Additional equipment may be made available by special arrangement with the PRT/IDT representatives. -Intro/4- Material Science (#146) Crystal Alignment (#148)—y Food Vending Lounge WASTE COLLECTION^ \ „ (#129) i AREA (#150) "^ FLOOR MANAGER / _ To Basement, Bldg. 535 Clean Room r~ (User Machine Shop) Chemistry (#149) (#128) (Vacuum Group) User Goniometer Storage, X1-X15 (#151 Op.Co./Cont.Rm.
