Solid Diamond Field Emitter

View page
US Patent:
6448700, Sep 10, 2002
Filed:
Oct 25, 1999
Appl. No.:
09/425410
Inventors:
Mool Chand Gupta - Yorktown VA
Ganapati Rao Myneni - Yorktown VA
Assignee:
Southeastern Universities Res. Assn. - Newport News VA
International Classification:
H01J 102
US Classification:
313309, 313336, 313351, 313495
Abstract:
The present invention provides a âsolidâ diamond, i. e. greater than 5 thick, electron emitter that has been âmachinedâ using non-contact techniques to a point having a radius of less than about 100, preferably below about 10 and most preferably between about 3 angstroms and about 3. The solid diamond electron emitters of the present invention can perform, even at these small radii, as multi-point emitters depending upon the radius and roughness of the pointed tip and can be used in arrays to obtain relatively large area field emitters for applications where such larger field emissions are necessary. Production of the solid diamond emitters of the present invention is preferably accomplished using non-contact electron or ion beam machining techniques. Residual gas analyzers (RGA) and field emitter extractor gauge analyzers (FERGA) that use the solid diamond emitters are also described.

Alternative Backing Up Pump For Turbomolecular Pumps

View page
US Patent:
6550256, Apr 22, 2003
Filed:
Aug 29, 2001
Appl. No.:
09/941344
Inventors:
Ganapati Rao Myneni - Yorktown VA
Assignee:
Southeastern Universities Research Assn. - Newport News VA
International Classification:
B01D 800
US Classification:
62 555, 417901
Abstract:
As an alternative to the use of a mechanical backing pump in the application of wide range turbomolecular pumps in ultra-high and extra high vacuum applications, palladium oxide is used to convert hydrogen present in the evacuation stream and related volumes to water with the water then being cryo-pumped to a low pressure of below about 1. e Torr at 150Â K. Cryo-pumping is achieved using a low cost Kleemenco cycle cryocooler, a somewhat more expensive thermoelectric cooler, a Venturi cooler or a similar device to achieve the required minimization of hydrogen partial pressure.

Passivated Niobium Cavities

View page
US Patent:
7151347, Dec 19, 2006
Filed:
Jun 28, 2005
Appl. No.:
11/168198
Inventors:
Ganapati Rao Myneni - Yorktown VA, US
Bjorgvin Hjorvarsson - Lagga Arby, SE
Gianluigi Ciovati - Newport News VA, US
Assignee:
Jefferson Science Associates LLC - Newport News VA
International Classification:
H01J 25/00
H01J 25/10
US Classification:
315500, 315 541
Abstract:
A niobium cavity exhibiting high quality factors at high gradients is provided by treating a niobium cavity through a process comprising: 1) removing surface oxides by plasma etching or a similar process; 2) removing hydrogen or other gases absorbed in the bulk niobium by high temperature treatment of the cavity under ultra high vacuum to achieve hydrogen outgassing; and 3) assuring the long term chemical stability of the niobium cavity by applying a passivating layer of a superconducting material having a superconducting transition temperature higher than niobium thereby reducing losses from electron (cooper pair) scattering in the near surface region of the interior of the niobium cavity. According to a preferred embodiment, the passivating layer comprises niobium nitride (NbN) applied by reactive sputtering.

Large Grain Cavities From Pure Niobium Ingot

View page
US Patent:
8128765, Mar 6, 2012
Filed:
Apr 5, 2005
Appl. No.:
11/099247
Inventors:
Ganapati Rao Myneni - Yorktown VA, US
Peter Kneisel - Williamsburg VA, US
Tadeu Cameiro - McMurray PA, US
Assignee:
Jefferson Science Associates, LLC - Newport, News VA
International Classification:
C22C 27/02
US Classification:
148668, 148422
Abstract:
Niobium cavities are fabricated by the drawing and ironing of as cast niobium ingot slices rather than from cold rolled niobium sheet. This method results in the production of niobium cavities having a minimum of grain boundaries at a significantly reduced cost as compared to the production of such structures from cold rolled sheet.

Ultra High Vacuum Pumping System And High Sensitivity Helium Leak Detector

View page
US Patent:
57032815, Dec 30, 1997
Filed:
May 8, 1996
Appl. No.:
8/646773
Inventors:
Ganapati Rao Myneni - Yorktown VA
Assignee:
Southeastern Univ. Research Assn. - Newport News VA
International Classification:
G01M 320
US Classification:
73 407
Abstract:
An improved helium leak detection method and apparatus are disclosed which increase the leak detection sensitivity to 10. sup. -13 atm cc s. sup. -1. The leak detection sensitivity is improved over conventional leak detectors by completely eliminating the use of o-rings, equipping the system with oil-free pumping systems, and by introducing measured flows of nitrogen at the entrances of both the turbo pump and backing pump to keep the system free of helium background. The addition of dry nitrogen flows to the system reduces backstreaming of atmospheric helium through the pumping system as a result of the limited compression ratios of the pumps for helium.

Cryogenic Liquid Level Measuring Apparatus

View page
US Patent:
50183877, May 28, 1991
Filed:
Jul 27, 1989
Appl. No.:
7/385372
Inventors:
Ganapati R. Myneni - Grafton VA
Assignee:
Southeastern Universities Research Association - Newport News VA
International Classification:
G01F 2300
US Classification:
73295
Abstract:
An apparatus for measuring a level of a cryogenic fluid in a cryostat includes a semiconductor pressure sensor mounted at the end of an elongated vertically disposed tube. The semiconductor pressure sensor is located at the bottom of the tube and is sealed in the bottom of the tube by a polymeric insulating material. The upper end of the tube is provided with a vent hole which communicates vapor pressure within the cryostat to the interior of the tube. The pressure sensor outputs an electrical signal in accordance with the differential pressure exerted on a semiconductor element of the pressure sensor from opposite sides by the vapor pressure within the tube and the fluid pressure outside the tube.

Metal Sponge For Cryosorption Pumping Applications

View page
US Patent:
54776929, Dec 26, 1995
Filed:
May 31, 1994
Appl. No.:
8/251798
Inventors:
Ganapati R. Myneni - Yorktown VA
Peter Kneisel - Williamsburg VA
Assignee:
Southeastern Universities Research - Newport News VA
International Classification:
B01D 800
US Classification:
62 555
Abstract:
A system has been developed for adsorbing gases at high vacuum in a closed area. The system utilizes large surface clean anodized metal surfaces at low temperatures to adsorb the gases. The large surface clean anodized metal is referred to as a metal sponge. The metal sponge generates or maintains the high vacuum by increasing the available active cryosorbing surface area.
