Comments on "Wall-plug (AC) power consumption of a very high energy e+/e- storage ring collider" by Marc Ross

TL;DR

This paper critically examines the power consumption estimates for the TLEP collider, reaffirming their accuracy based on CERN's experience and challenging alternative assumptions.

Contribution

It defends the original power consumption estimates of TLEP by referencing CERN's accelerator experience and clarifies the assumptions used.

Findings

Original TLEP power estimates are supported by CERN data.

Assumptions used in power estimation are solid and justified.

Counterarguments to alternative assumptions are addressed.

Abstract

The paper arXiv:1308.0735 questions some of the technical assumptions made by the TLEP Steering Group when estimating in arXiv:1305.6498 the power requirement for the very high energy e+e- storage ring collider TLEP. We show that our assumptions are based solidly on CERN experience with LEP and the LHC, as well accelerators elsewhere, and confirm our earlier baseline estimate of the TLEP power consumption.
