IGI-9600® Polarizers

Currently we have three IGI-9600® polarizers (Inert Gas Imaging) located at our facility. One is an early prototype created in 1997, the other two are recent designs created in 1999 and 2000 by Amersham Health Imaging. The 1997 system consists of a main cart with all the systems and instruments and two distinct removable cartridges, one for the 3He polarization and the other for the 129Xe polarization. Each cartridge supports a specific glass cell and a gas dispensing apparatus. The picture to the right shows the 1997 cart with the 3He cartridge mounted (white color). On the left side of the cart is the 129Xe cartridge.

The picture and the respective diagram of the optical instruments, Helmoltz coils, and glass cell oven is shown on the left. The 795 nm laser beam is circularly polarized after passing through a quarter wavelength plate. The system uses a 100 Watt diode laser.
For more details about the polarization, see the Polarization Process page.

All uses of this system are presently limited by federal law to investigational use only.
