Overview of the MEC instrument layout. Distances are indicated in meters from the interaction region (IR). M is the last off-set mirror, D are non-destructive intensity and alignment diagnostics, S&D are slits and non-destructive intensity diagnostics, TT is a timetool to measure the arrival time of the Ti:S laser relative to the X-ray pulse, Lenses are beryllium compound refractive lenses, M1 and M2 are mirrors to reject the ∼1% third harmonic that is present in the LCLS beam, WIN is a 25 µm Be window, and IR is the standard interaction region (i.e. the center of the MEC target chamber). The interaction region is located approximately 460 m downstream of the undulator.
