Systems, assemblies and methods for thermally managing a grazing incidence collector (GIC) for EUV lithography applications are disclosed. The GIC thermal management assembly includes a GIC mirror shell interfaced with a jacket to form a sealed chamber. An open cell, heat transfer (OCHT) material is disposed within the metal chamber and is thermally and mechanically bonded with the GIC mirror shell and jacket. A coolant is flowed in an azimuthally symmetric fashion through the OCHT material between input and output plenums to effectuate cooling when the GIC thermal management assembly is used in a GIC mirror system configured to receive and form collected EUV radiation from an EUV radiation source.

The amount of power being output to the load is sensed by sampling the frequency of the pulse width modulation signal that is controlling the switch that is providing the power to the load. If the pulse width modulation signal has a high frequency, then it will be providing higher power to the load. As the power drawn by the load decreases, the frequency of the pulse width modulation power supply signal will decrease. By sensing and periodically sampling the frequency of the pulse width modulation signal that is providing power, the demand of the load can be quickly and accurately determined. As the power demand of the load decreases, the peak current that the power supply switch can provide also decreases. The permitted peak current dynamically changes to adapt to the power drawn by the load.

Evaporate thermal management systems for and methods of grazing incidence collectors (GICs) for extreme ultraviolet (EUV) lithography include a GIC shell interfaced with a jacket to form a structure having a leading end and that defines a chamber. The chamber operably supports at least one wicking layer. A conduit connects the wicking layer to a condenser system that support cooling fluid in a reservoir. When heat is applied to the leading end, the cooling fluid is drawn into the chamber from the condenser unit via capillary action in the wicking layer and an optional gravity assist, while vapor is drawn in the opposite direction from the chamber to the condenser unit. Heat is removed from the condensed vapor at the condenser unit, thereby cooling the GIC mirror shell.

The invention relates to a gear-toothed rod stepless automatic transmission, which comprises a first bracket, a second bracket, two input discs, two output discs, a second transmission shaft, a first transmission shaft, a first transmission gear, a second Two transmission gears; two input disks are respectively installed on both sides of the first bracket; two output disks are connected with the second bracket through the first transmission shaft, and are respectively installed on both sides of the second bracket; the disk surfaces of the input disk and the output disk There are multiple sector rack areas; one end of the second transmission shaft is connected to the first bracket, and the other end is connected to the second bracket. The first transmission gear is slidably installed on the second transmission shaft and connected to the two input The racks of the discs mesh with each other, and the second transmission gear is slidably mounted on the second transmission shaft and intermeshes with the racks of the two output discs. The gear-tooth movable rod stepless automatic transmission of the invention has high power transmission stability and can transmit relatively large power loads.

A ceramic discharge lamp and a method of making the lamp includes a ceramic discharge chamber with two concave parts that are attached to each other at a seam, and a ceramic reflector directly attached to an exterior surface of the discharge chamber at the seam, or directly attached to a ceramic capillary that is attached to one of the two concave parts. The lamp finds particular application where focused light is required, such as injection of light into a fiber optic device. The lamp can be very small and has an advantage that the discharge chamber is isolated from the reflective surfaces so that the optically active parts of the reflector are not covered with salt from the preferred metal halide lamp fill.
