History
1948
Varian Brothers Introduce the Klystron
Russell H. Varian and Sigurd F. Varian the historical founders of CPI’s business, found Varian Associates and introduced the klystron, which they invented, as its first commercial product. At the time, Varian Associates has $22,000 of capital and six full-time employees.
1950s
Early Operations Grow Quickly
In its early years, Varian Associates’ products include vacuum electron tubes, an expanding instruments product line, an embryonic accelerator activity and a venture into geophysical instruments. In the mid-1950s, the company invents an all-electronic vacuum pump for manufacturing vacuum electron tubes. The company soon realizes that the vacuum pump had applications far beyond tube processing and launches additional lines of business.
1953
Company Establishes Headquarters in Palo Alto, California
The company moves the headquarters of Varian Associates to what is now the Stanford Research Park in Palo Alto, California. CPI’s present-day headquarters remain on the same campus.
1954
Varian Associates of Canada Launches in Ontario, Canada
In the early 1950s, the Canadian government asks Varian Associates to create a local source for the production of microwave vacuum electron devices. The company establishes Varian Associates of Canada Limited in 1954 in Georgetown, Ontario, Canada.
1959
Varian Associates Establishes Operations in Beverly, Massachusetts
Varian Associates acquires Bomac Laboratories, a manufacturer of microwave tubes and components, and helps launch S-F-D Laboratories to design and build new classes of magnetrons and other microwave tubes. These operations are combined with LEL, Inc., which specializes in microwave components and is acquired by the company in 1964, to create one operation in Beverly, Massachusetts.
1960s
Company Explores New Avenues for Growth
Varian Associates expands its business with research in solid state devices, new forms of printing and the development of devices for commercial communications. The company also acquires the traveling wave tube business of the General Electric Company in Palo Alto during this period.
1965
Varian Associates Acquires Eitel-McCullough (Eimac)
William Eitel and Jack McCullough found Eitel-McCullough, Inc. in 1934 to produce more powerful and reliable transmitting vacuum tubes operating at low voltages for the Ham radio community. Its products are quickly adopted for commercial and military transmitters; they are used by the U.S. Navy in radar experiments starting in 1938 and they power Allied radars during World War II. By 1965, Eimac manufactures a broad line of specialty electron tubes, primarily for various broadcast and industrial markets.
1970s
Early Solid State Operations
In 1972, Varian Associates purchases Ryka Scientific, which becomes part of the company’s solid state operations. In 1979, these operations are consolidated and move into a new facility “dedicated to the development and production of microwave solid state devices and components.” These products are used for low-power applications in communications, avionics, radar, instrumentation and electronic warfare applications. CPI later sells these operations.
1989
Eimac Wins an Emmy
The Eimac Division of Varian Associates is awarded an Emmy® Award for technological achievement by the Academy of Television Arts and Sciences for the energy efficient performance of the Klystrode® inductive output tube (IOT). The Klystrode IOT used in television transmitters at WCES in Augusta, Georgia is the first of the high-power output devices to be on-air for UHF television.
1995
CPI is Formed
Varian Associates sells the Electron Device Business to Leonard Green & Partners, L.P., a private equity fund, and members of management. Together, they form Communications & Power Industries (CPI) with the mandate to continue to grow the business’ tradition of technology leadership and manufacturing excellence.
