Figure 2
The layout of the PXS. The U-shaped vacuum chamber contains the spools of the copper tape, as well as shielding Mylar tapes that protect the entrance and exit windows from copper dust. The OAP focuses the laser onto the copper tape through the AR-coated vacuum window. The laser interaction point is marked by a star. The X-rays are emitted at a 4π solid angle. Radiation exits through the two Kapton-sealed slits, towards the experiment and diagnostics. The capacitive sensors are marked with red rectangles, if switched by the spool size, and green rectangles, if not activated. |
