Fermilab’s new Horizontal Test Stand sees its first cavity

The newest resident in Fermilab’s Meson Detector Building is up and running. Last week, Fermilab scientists installed a nine-cell 1.3 GHz TESLA-style cavity into a cryostat in order to commission the new Horizontal Test Stand. Designed to test both 3.9 Ghz and 1.3 Ghz 9-cell niobium cavities, the Horizontal Test Stand will play an important role in the growing ILC R&D programme at Fermilab.

Feature Story
Sports car treatment for cavities

Challenges are all around for cavities that want to perform well. The material they are made of, the way they have been cleaned, they way they are shaped and they way their cells are welded together all influence the way the electrons fly through them. A process called hydroforming might be a means to tackle the last two threats, and a small team from DESY has just created the first all-niobium hydroformed nine-cell cavity.

Hot Spots
A little hint, and we got flooded with responses! A temperature map indeed, showing hot spots on a cavity at Cornell University. Congratulations to Marion White of Argonne who was the first person to send us the correct answer. Thank you to everyone else who participated!

Think you can stump NewsLine readers with an ILC-related photo? Send us your candidates for “What is It?” and we will use them in a future issue of ILC NewsLine.

How to survive in a black hole
So there you are: you discover that your spaceship has inadvertently slipped across the event horizon of a black hole - the boundary beyond which nothing, not even light, can escape the hole's fearsome gravity.

Director's Corner
Troika proposed to manage ILC engineering design

A troika, a Russian sled drawn by three horses
Developing an engineering design for the ILC represents a formidable challenge with many hurdles in our path. We must satisfy the different goals of our collaborating countries, maintain regional balance, keep flexibility to be responsive to results from the LHC and prioritise our R&D resources to support the design. Lastly, we must develop a robust engineering design, while maintaining a very aggressive schedule. There are just too many separate tasks involved for a single manager to oversee the effort and therefore we are proposing to literally borrow the famous Russian symbolism of a “Troika,” and create a Project Office consisting of three project managers: Marc Ross (Fermilab), Nick Walker (DESY) and Akira Yamamoto (KEK). This team will have both shared and separate responsibilities, and Marc Ross will serve as the initial chair of the group.

LCWS2007 and ILC2007
The workshops LCWS07 and ILC2007 take place in Hamburg from 30 May to 3 June. Agenda are available online.

ALCPG07 is the next in a continuing series of North American regional meetings on the physics, detector and accelerator issues of the future International Linear Collider and will be held at Fermilab on 22-26 October. A meeting web site is now available, although online registration will not be available until 20 June.
