Radiation Effects Testing and Calibration
This facility is available for the study of space radiation effects, in particular, Single Event Upset ( SEU ) Testing and Spacecraft Instrument Calibration. We can provide ion beams for more than 50 ion species at a wide range of energies and intensities. Our capabilities range from 29 MeV protons to 385 MeV uranium. See our run calendar for times when the facility may be available. You can also see when the facility may be available by looking at SEU Availability. To get more information about our capabilities and services, use the more info request form. Registered users with existing accounts can reserve beam time using the time request fill-in form.

Our facility is frequently upgraded and improved in response to suggestions from our user community. If you have any suggestions about how we can improve our services, please let us know how we can assist you to make your experience at the TVDG more pleasant and rewarding.

Listed below are several examples of the type of work that is done at the SEU Test Facility.

 

Have you got questions? We have answers. See our SEU FAQ (Frequently Asked Questions) page for information about the SEU hardware and software.

Ion Irradiation/Implantation
Our facility is also available for other ion-beam related applications. You may contact us to discuss the requirements for your project or product. We will be happy to provide you with any development assistance you may need. You can arrange to discuss your project with a member of our staff of engineers and scientists who have an extensive background in ion irradiation and implantation. We can help you with every stage of development from concept to working system.

Heavy Ion Research
Nuclear physics started at this facility in 1970. Since 1986 one of the accelerators (MP-7) serves as the heavy ion injector for the Brookhaven synchrotrons (AGS Booster, AGS , and eventually for RHIC - the Relativistic Heavy Ion Collider). The synchrotrons are host to a number of nuclear physics and heavy ion experiments at relativistic energies.

The NASA Space Radiation Laboratory at Brookhaven National Laboratory studies the effects of relativistic heavy ions on cells and animals. This radiobiology research program is related to the investigation of space radiation on humans and is particularly important for the planning of future long-term deep space flights. See the NSRL website for more information.

About Us
The BNL Tandem Van de Graaff (TVDG) Facility consists of two model MP (MP-6 and MP-7) electrostatic accelerators, their associated beam transport lines, experimental areas and test facilities. The TVDG complex was originally constructed by High Voltage Engineering Corporation (HVEC) in the mid 1960s and has undergone upgrades and improvements ever since. HVEC was founded by Robert J. Van de Graaff.

A major improvement was the addition of a Pelletron charging systems to both accelerators. This link is a nice .gif animation of the operation of the charging system.

Both accelerators (MP-6 and MP-7) have been upgraded to run at a maximum terminal voltage of 15 MV and are also capable of high intensity pulsed beam operation. Both accelerators are currently in service providing beam for SEU users as well as delivering gold and deuterons to RHIC. The facility can now support the Booster/AGS/RHIC/NSRL program and the outside user program simultaneously. This will allow us to run SEU and other applied programs year round. A layout diagram of the upgraded facility is available in .doc (MSWord) format.

How To Get More Information
We will be happy to provide you with more detailed information about our facility and capabilities. To request additional information, please use the more info fill-in form or contact us and tell us about your project and how our services can help you.

If you are a registered user, you can request beam time by using our Time Reservation form. If your browser is forms-challenged or you prefer the convenience of e-mail, please request this information by sending an e-mail to ccarlson@bnl.gov.

You can also look at the Introduction to the TVDG for additional information about our facility.

A short biography of Robert J. Van de Graaff is now available. This is a chronology of his life where you can learn something about the man who invented the electrostatic particle accelerator.

A very nice general reference site about Van de Graaff Generators is available. Some of this site is in French and some in English.
