PEP Insertion Quadrupole Design Features

New Petri Net Programming Features in PEP ?

We present two new facilities of the high level Petri net editor of the PEP tool. The latest version extends the class of supported Petri nets by a time extension of M-nets. Additionally it features a new operator for asynchronous communication complementing the synchronization operator. We present an example of an ARQ protocol with enhanced acknowledgment handling. form.

Real-Time Systems Design with PEP

Design of the Pep-ii Low-energy Ring

The PEP-II Project, a collaboration of SLAC, LBL, and LLNL, began construction in January 1994. Since the Conceptual Design Report (CDR) [1] was issued in June 1993, considerable progress has been made at refining and optimizing the Low-Energy Ring. Lattice design has progressed considerably, with solutions obtained for the chromatic correction of the IR and new, more relaxed, parameters for th...

PEP-II B-Factory Prototype Higher Order Mode Load Design*

To reduce the impedance of the cavity higher order modes, (HOM’s), a compact broad-band, low-reflection, waveguide load is required with a VSWR less than 2:1 in the frequency range 714 MHz to 2500 MHz. The load must also work in the high vacuum of the cavity, and be capable of dissipating up to 10 kW of power which is generated by the the interaction of the beam with the cavity HOM’s and which ...

A First Design of the Pep-n Calorimeter

A preliminary design of the PEP-N electromagnetic calorimeter is given. The spatial, energy and time resolutions achievable using a KLOE type electromagnetic calorimeter are presented. 1 PHYSICS REQUIREMENTS AND PERFORMANCE GOALS Figure 1: Angular (rad.) energy (GeV) photon correlation for ee → 2π2π2π. The main goals of the PEP-N physics programs are : • a measurement of R with a 2 % or better ...
