TITLE: GPT Best Practices

SPEAKER: Dr. Bas van der Geer, Author, General Particle Tracer Software

ABSTRACT: Over the past two decades the General Particle Tracer (GPT) code has become a well-established simulation platform for the design of charged particle accelerators and beamlines. However, a significant increase in hardware complexity, in addition to ever increasing demands from the accelerator community, make it more and more challenging to maintain a generic code that performs well over a broad range of applications. On the one hand we are proud that GPT is being used for both the simulation of keV electron microscopes and GeV class accelerators, but on the other hand we see an increasing number of performance related problems where simple changes in beam line modelling and numerical settings can severely impact the performance of the code. This presentation focuses on the design philosophy of GPT, explaining why certain approaches work better than others. Topics include modelling external fields, stochastic Coulomb interactions, the PIC space-charge model, running the multi-objective optimiser, load-balancing on MPI clusters, and any application of GPT proposed by the audience.

TITLE: Highlights and Reflections of the EIC Accelerator Collaboration meeting 2017

SPEAKER: Yuhong Zhang, Center for Advanced Studies of Accelerators, Jefferson Lab

ABSTRACT: An Electron-Ion Collider (EIC) accelerator collaboration meeting was held October 10 – 12, 2017 at Brookhaven National Laboratory (BNL).  This was the first collaboration meeting jointly organized by BNL and Jefferson Lab for both eRHIC and JLEIC designs.  In this seminar, the speaker will show highlights of this collaboration meeting as well as share some of his personal reflections.  At the end of the seminar, the speaker will lead discussion about the impressions of other meeting attendees.
