Introduction to CEBAF BLM System

• Brian Freeman

Room: L102 Requirements, design, implementation (cover both protection and diagnostics BLMs)

Beam Loss Mechanisms

• Yves Roblin

Room: L102 "1. Beam loss mechanism contributing to downtime a. What we know (anlaysis, evidence) b. What we do not know c. What we need to know 2. Specific beam transport issues contributing to beam losses"

Specifications and BLM Calibration Procedure

• Jerry Kowall

Room: L102 1. BLM system specifications a. Are specifications appropriate to prevent damage, activation b. Do we understand impact of losses (damage, activation) sufficiently well 2. Calibration procedure a. Are our calibration procedures appropriate (not too lax or conservative)"

Analysis of BLM System Performance

• Katheryne Price

Room: L102 1. Identify and evaluate performance gaps (with goals to protect CEBAF and allow tuning) 2. Does the BLM MPS system perform as expected? a. Is it overprotecting, under protecting, or works just right? b. Do we have unnecessary trips what we think are unwarranted c. Do we have accelerator unexpected/unwarranted damages d. Do we have unexpected activation of the accelerator 3. Does the system design of the system allow for efficient tuning 4. Are there deficiencies in the system layout or/and design that limit its performance?"

BLM System Maintainability and Obsolescence

• Roger Araiza

Room: L102 1. Are there issues with BLM system maintainability. How can maintenance be improved if necessary 3. What are obsolescence issues that need to be addressed"
