GENERAL DESCRIPTION:	BL6-2 has an in-vacuum LN2-cooled monochromator and is windowless up to a 127 mm Be window in the hutch. For high-energy applications, a toroidal Si M1 mirror is used as post-monochromator focusing element. For soft-energy applications, the M2 mirror is used for harmonic rejection.
Sample Preparation Labs:	The SSRL Structural Molecular Biology (SMB) Sample Preparation Laboratories are available to users by prearrangement. To use a laboratory, users must complete laboratory training, and provide a list of all chemicals to be brought, used or stored in the Sample Preparation Laboratory. For details, contact Cynthia Patty (650-926-3925).
