NEH 1.1 beamline will have two separate instruments with the fixed X-ray beam positions – NAMASTE and DREAM. Some baemline components and diagnostics will be placed in the front end enclosure (FEE) as shown in the functional layout below. In the hutch the NAMASTE endstation will be situated upstream, while the DREAM endstation will be located downstream. Each endstation will have a separate set of KB focusing optics, together with the individual suite of post-interaction region diagnostics.
The NEH 1.1. NAMASTE endstation will offer the possibility to install modular stations (roll in and out) which can be set up, aligned and commissioned outside the hutch and installed at the first TMO focus spot. Therefore, these modules have to be highly standardized and will accept gas phase and solid samples.
DREAM instrument will be designed while keeping in mind a more stringent requirements of a COLTRIMS type coincidence experiments – UHV of 10-11 – 10-12 Torr pressure, thin gas jet (<1010 per cc) or solid target, sub-micron X-ray focus. While DREAM will be made compatible with several types of spectrometer the system will be considered much less flexible than NAMASTE when it comes to the configuration changes and will require longer time between experiment setup alterations. Typical dynamic molecular reaction microscope spectrometer of DREAM station will be capable of taking full advantage of the LCLS II high rep rate.
Both endstations as well as their diagnostics will have flexible 6 Degree of Freedom (6-DoF) stands. Timing tools will be provided for optical-pump / X-ray probe experiments in either chamber. Also part of the diagnostic are WFS and Power Meter.
The following figures present functional and physical layouts of the NEH 1.1 beamline, TXI beamline components are minimally shown to emphasize the space interplay between NEH 1.1 and 1.2.
