IPNS FAST ACCESS PROCEDURE

A procedure has been implemented for performing fast turn-around experiments on the following instruments:

• General Purpose Powder Diffractometer (GPPD)
• High Intensity Powder Diffractometer (HIPD)
• Neutron Reflectometer (POSY II)
• Small Angle Neutron Diffractometers (SAD/SAND)
• Special Environment Powder Diffractometer (SEPD)

A small fraction of the operating time on each of these instruments will be available on a first-come first served basis, without the need to submit the standard 4-page proposal form. A short, 1-page form will need to be completed indicating any potential hazards. Interested users should contact the specific instrument scientist to learn the backlog for each instrument. Samples will be shipped to IPNS and data collection will be done when time becomes available without the user coming to IPNS. The raw data can then be accessed on the instrument computer. Similar to other experiments performed at IPNS, users will be responsible for data analysis. This service will be limited to short (less than one day) experiments involving only room-temperature data collection for samples that present no special handling problems. The time allocated to a single user will be limited to allow access for as many different users as possible.
