摘要： A cryopump installation in which a novel cryopump 20 maintains a work chamber 12 at continuous high vacuum while periodically evacuating a load lock 14 in order to allow transfer of material from the load lock 14 to the work chamber 12 without disruption of the work chamber environment. The cryopump has pumping ports 46 positioned on the radiation shield 50 in order to pump plenum 72 to a high vacuum. Load lock gases enter the cryopump through port 46 and are condensed and adsorbed by the radiation shield 50 and second stage cryopanel 54.

摘要： To control the temperature of one or more heat sinks of a cryogenic refrigerator in a cryopump, refrigerant gas to the refrigerator is diverted through heat exchangers associated with the refrigerator heat sinks. The diverted refrigerant gas may be used to maintain the temperature of the first stage cryopumping surfaces above some level to avoid cross over hangup. The second stage cryopumping surfaces may be warmed by the diverted refrigerant to some temperature level for partial regeneration. Both heat sinks may be warmed for full regeneration of the cryopump. Bleed flow of refrigerant gas cooled by the first stage of the refrigerator can be directed past a thermal mass to cool that mass. By reversing the flow of refrigerant gas during cooldown of the system, the thermal mass can be used to more rapidly cool the refrigerator. The thermal mass is thermally isolated from the refrigerator heat sinks and is positioned within the vacuum vessel of the cryopump adjacent to the first stage of the refrigerator.
摘要翻译：为了控制低温泵中的低温冰箱的一个或多个散热器的温度，通向与冰箱散热器相关联的热交换器将制冷剂气体输送到冰箱。转向的制冷剂气体可用于将第一级低温泵的表面的温度保持在一定程度上，以避免交叉悬挂。可将第二级低温泵送表面由转向制冷剂加热到一定温度以进行部分再生。这两个散热片可能会被加热，以便低温泵完全再生。由冰箱的第一级冷却的制冷剂气体的流出可以被引导通过热质量以冷却该质量。通过在系统的冷却期间逆转制冷剂气体的流动，可以使用热质量来更快速地冷却冰箱。热物质与冰箱散热器热隔离，并且位于与冰箱的第一级相邻的低温泵的真空容器内。

摘要： A cryopump 20 for differentially pumping water vapor and inert gases from a work space comprising a two stage refrigerator 45 in which a radiation shield 32 substantially encloses a second stage cryopanel 40. The radiation shield 32 incorporates a baffle plate 34 which condenses higher condensing temperature gases and restricts passage of low condensing temperature gases through orifices 36 to the second stage cryopanel 40. Backside pumping ports 38 provide a flow path to the second stage refrigerator for residual gases within the cryopump 20. This creates a high vacuum within the cryopump and allows it to operate at maximum efficiency.

摘要： A system and method of use for determining a desired physical parameter relating to a load deployed by a movable vessel, in a predetermined plane, using a sensor disposed proximate the load underwater where the sensor produces a transmittable signal indicative of the desired physical parameter and communicates the signal, via a communication link, to a receiver that receives and indicates the pressure signal. A deployment frame may be used to further support the load. Once deployed, the load encounters water having changes in the detected physical parameter and the sensor sends a signal indicative of the changes such as to a controller or computer located on a movable vessel. These signals can be used to determine movement and positioning of the load, e.g. when positioning the load proximate an underwater structure. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims.
