US Navy Contracts Polarity, Inc.
The US Navy awarded Polarity with a contract to design and build their new advanced magnetron test systems. These magnetron test systems will use Polarity's high performance solid state modulator and 10KW, 40KV cathode power supply. Contract issuance through 2005. _________________________

Polarity Now Offering TWT Test Sets:
Polarity, Inc. is now offering TWT test sets that have a 15KV cathode power supply, 3ea-3KW collector power supplies, 3KV swing grid modulator, and a 8V, 8A heater supply. This product was developed as a low cost solution for the TWT manufacturing industry. _________________________

Polarity Acquires New Manufacturing Facility:
Polarity, Inc. acquires new facility that increases our engineering and manufacturing square footage by four times. Located in Rancho Cordova, Polarity, Inc. is scheduled to be in the new space by February 1, 2004. See company profile page. _________________________

Polarity Improves and Expands Employee Benefit Program by Contracting with Administaff, Inc.: Polarity, Inc. now offers an expanded employee benefit program including payroll services, medical/dental/ vision benefits, 401K plan, and HR administration support to meet the growing needs of it’s current and future employees. _________________________

Industrial/Commercial Power Supplies 
Now Offered:

Polarity, Inc. is now offering 300V, 100W and 600v, 100W industrial power supplies. These power supplies are being used by the United States Navy for pulse mode applications. Polarity is also offering a commercial version of these power supplies.

Third Generation 1MHz, 2.5KV RF Source Complete:
Polarity completed its third generation 1MHz, 2.5KV RF source that integrates with TOF Mass Spec systems. The rack mount RF Source has a built in crowbar system that is connected electrically across the RF output. It is used to clamp the RF output to less 30V in less than 500ns. Crowbar triggering can be accomplished before the output extraction pulse so that system propagation delay can be accounted for to successfully detect and analyze negative ions. This will enable the BIOresearch firms to look at different proteins with TOF Mass Spec technology.
