Mail-In EXAFS Service

The Mail-in EXAFS Service is another facility provided at the National Synchrotron Light Source, Brookhaven National Laboratory. This is offered to any person interested in doing X-ray absorption spectroscopy but has no time or other reasons to go to a synchrotron and do it by themselves. You can prepare your samples according to the directions given on the Thickness Measurements page, mount it on a standard holder and mail it to us with all possible details. You should always include some standard samples along with your unknowns for your data analysis and its interpretation. We will collect EXAFS and XANES data for you at room temperature or low cryogenic temperatures, as the need may be, and we will return the samples to you, along with the data, in any format you specify.

At the moment we are doing this in transmission mode only.

The energy range for K-absorption edges is from P (2.142 KeV) to La (38.931 KeV) and for LIII- absorption edge is from Zr (2.220 KeV) to U (17.163 KeV) + all other trans-uranium elements.

Following are the EXAFS scans of some standard foils taken at Beamline X18B

Data Base EXAFS Standards

The standard foils and filters available at the NSLS are listed at the NSLS-EXAFS Equipment Pool. If the Mail-in EXAFS Users prefer they can ask for doing EXAFS/XANES of those standards along with their samples.

Actual cost to provide the service will be billed. Please contact Syed Khalid for an estimate of the costs to provide this service. The total time to run the samples depends upon the concentration of the samples, detector and equipment setup and other requirements of your experiments. The samples can be done when the X-ray operational beam time is available at X18B or at X19A. Please see the schedules of these beamlines at the X18B Home page.

The Rates are about $100.00/hour.

IMPORTANT: To run your samples you must have a BNL Operating Account for the NSLS.


User Accounts

Operating Accounts (81000 accounts)
General Users who are allocated beam time and Participating Research Teams (PRTs) or Contributing Users (CUs) who operate beamlines should establish a BNL operating account to cover the costs of materials while running an experiment, shipping, and/or miscellaneous BNL services (telephone & fax codes), if these needs are anticipated. The term of the purchase order must be specified and names of persons having signature authorization for charges against this account must be listed.

Brookhaven's Fiscal Division will bill the user for any charges the user makes to the account. Users are obligated to pay outstanding debts promptly.

All users should set up a $1,000 operating account to cover operating expenses while at the NSLS, such as charges for use of trades, shops, and Stockroom withdrawals. A telephone access code, for use in placing off-site calls and faxes, is associated with each operating account. Operating accounts, which are subject to BNL overhead, are established by the user's home institution via a purchase order. All orders for an operating account must contain the following:

  • Sufficient information to identify type of account (e.g. PHOBOS Experiment, NSLS User, Beamline X23 PRT, Proprietary research, services of..., identity of contact person, or facility being visited, etc...)
  • Full names of authorized users. Identify the Principal Investigator
  • Total dollar amount
  • Expiration date of order
  • Complete billing instructions

To open an account, forward a purchase order to the address below.

Proprietary Research Accounts (85000 accounts)
Any beam time used for proprietary research purposes must be charged the full cost recovery rate* against a proprietary account. Users should set up such an account at the same time, or preferably before, they submit a Proprietary Research Proposal. A 100 percent advance of the estimated annual usage of proprietary research hours is required to be in the account before proprietary work can begin. This is required as stated in the US DOE Accounting Handbook, Chapter 13. A single account may be used to cover one or more proprietary proposals over an extended period of time. These accounts, like operating accounts, are established by the user's home institution via a purchase order. Information regarding set up of these accounts can be obtained from the BNL Budget Office at 631-344-7957.

For Participating Research Teams, the spokesperson is responsible for having a proprietary research account at BNL, separate from their operating account, to suitably cover proprietary research charges they will incur. A single proprietary research account may be used for one or more proposals, either at the same time or consecutively. The spokesperson must arrange to use an existing account associated with their institution or they must create a separate account. To set up an account forward a purchase order to BNL's Budget Office, allowing two weeks for processing at BNL. The purchase order should clearly state:

  • P.I. on account and who will have signature authorization for charging expenses against this account
  • that it is for proprietary research expenses
  • the authorized charge ceiling of the account
  • the expiration date of the order

All proprietary users are required to report proprietary usage, or for PRTs, confirm non-usage, each month. Proprietary users are contacted via email by the NSLS Proposal Coordinator to verify running dates and times according to SAFs run in the previous time period. Proprietary time is required to be billed each month according to the U.S. Department of Energy's Accounting Handbook, Chapter 13.

Please note a one-hour set-up charge and one-hour take-down charge is applied to EACH proprietary run. When 5 minutes or more have elapsed into the next hour, it is considered to be one full hour.

Capital Accounts (89000 accounts)
Capital accounts are used for fabrication of equipment and components that become part of the beamline. These accounts are established through a purchase order between the user's home institution and BNL according to a pre-arranged agreement and cost estimate. These accounts are subject to BNL overhead charges. Questions regarding these accounts should be addressed to x7957.
