Other Features:

Extracted beam energy changes can be done in less than 30 minutes.
Beam intensity monitored with an air ion chamber calibrated against plastic scintillators or a miniature calibrated ion chamber.
Beam profiles monitored by integrating multiwire chambers.
Laser or optical alignment of components on beam axis.
Dedicated electronics and data display.

High Intensity Proton Beams:

In order to accommodate requests for fluences of protons at the 10¹³ protons/cm² level in a reasonable time, a high intensity irradiation position has been developed for both BL2C and BL1B. The beam spot is smaller (typically 1-2 cm in diameter), but the flux is 10 x larger than the flux at the normal irradiation location.
