    摘要: A nuclear camera system (10) includes a gantry (22, 23) disposed about an examination region (17) having detector heads (15 a,b,c) mounted to the gantry. The detector heads (15) include an enclosure (30, 34, 54, 56) defining a volume (61). A plurality of solid state detectors (40) are arranged in an array (36) within the enclosure volume. A first cold plate (46) is in thermally conductive contact with the plurality of solid state detectors. A first Peltier cooler (50) is in thermally conductive contact with the first cold plate, the first Peltier cooler provides for cooling the plurality of detectors in the array. A second cold plate (47) is located within the enclosure and is thermally insulated from first cold plate. A second Peltier cooler (52) is in thermally conductive contact with the second cold plate, the second Peltier cooler for removing moisture from the volume (61). A heat sink (56) is in thermally conductive contact with the first and second Peltier coolers. A sensor (64, 66, 68, 75) is in operative relationship with the detector head. The sensor (75) provides a signal indicative of an environmental condition within the interior volume of the detector head. A controller (24) is controllably connected to the sensor. The controller determines a modification, modification in response to the sensor signal, to a selected environmental condition within the interior volume of the detector head and provides a control instruction for the modification. An actuator (52, 66, 73) is in operative relationship with the interior volume of the detector and is controllably connected to the controller. The actuator implements a control instruction from the controller for modifying the selected condition within the detector head.

    摘要: Embodiments provide systems, devices, and methods for controlling a laser. The system includes a controller to control a laser, a ramp generator to ramp down laser power, the ramp generator electrically coupled with the controller and coupleable with the laser, and a hardware protection system electrically coupled with the ramp generator, wherein the ramp generator monitors signals sent from the controller and the hardware protection system to the ramp generator to detect signal failure and ramps down the laser power upon signal failure detection. The method includes sending a control status signal from a controller for a laser to a ramp generator, monitoring the control status signal for missing pulses, sending a hardware interlock status signal from a hardware protection system to the ramp generator, monitoring the hardware interlock status signal for signal failure, and ramping down laser power upon detection of missing pulses or signal failure.

    摘要: Apparatus and methods for detecting lamp failure in a rapid thermal processing (RTP) tool are provided. Lamp failure detection systems are provided that can accommodate DC and/or AC voltages. The systems sample voltage signals along a circuit path formed by at least two serially connected lamps, calculate a voltage drop across the first lamp of the at least two serially connected lamps based on the sampled voltage signals, and determine whether a lamp failure has occurred based on a relationship between the voltage drop across the first lamp and a total voltage applied to the circuit path.
