The PEP transducer.

The PEP transducer: a new way of measuring respiratory rate in the non-intubated patient.

OBJECTIVES To explore the use of a pyroelectric polymer (PEP) film as a transducer for a simple respiratory rate monitor and to evaluate the transducer in a laboratory situation. METHODS Laboratory evaluation of a new pyroelectric transducer for measurement of respiratory rate. RESULTS The amplified output from the pyroelectric film produced an excellent respiratory trace when used on a nor...

SPEAR II and PEP Klystron Parameters PEP Klystron Interaction Space Parameters SPEAR II PEP

The 125 kW CW klystrons to be described in the first part of this paper were specifically designed for energy upgrading of the electron-positron storage ring, SPEAR II, at SLAC. Four tubes are required with an efficiency greater than 50 percent. The operating frequency is 358.54 MHz. The gain is approximately 50 dB, the operating voltage is 41 kV and the microperveance is 0.7. The klystron must...
