Large-Grain Niobium Cavities Receive Strong Endorsement
Global experts discuss niobium production and progress made on single-crystal and large-grain niobium technology at workshop in Brazil.

Students from the CBMM daycare center, an onsite facility for employees' children, enthusiastically welcomed the workshop attendees. The group also participated in a tree-planting ceremony as part of the niobium manufacturer's nature conservancy program.
On the pursuit to design and build a superconducting cavity that will consistently reach the required acceleration gradient of 35 megavolts per metre for the International Linear Collider, a group of 30 scientists from eight industrial companies and nine research laboratories recently came together at the world's largest niobium mine in Araxá, Brazil for the Single-Crystal Niobium Technology Workshop. The workshop educated attendees about the niobium production process and facilitated a dialogue about the development of single-crystal and large-grain niobium for ILC superconducting cavities.

ILC Detectors in the Making: LDC is Going with the Flow

Artist's impression of the LDC detector.
In July, ILC NewsLine provided an overview of the Global Large Detector (GLD) concept. In October we took a closer look at the Silicon Detector (SiD) concept. This week features the third ILC detector concept LDC, and ILC NewsLine will continue its series about the four ILC detector concepts in the weeks to come. Next: 4th detector concept.

With a concept called particle flow, experimenters at the ILC are getting philosophical. Particle flow, according to them, is the philosophy of event reconstruction. In the future ILC detectors, scientists will not rely on the classical event reconstruction methods of tracks in the tracker and energy dots in the calorimeter. They want more - a complete 3-D reconstruction of every charged and neutral particle that went through their carefully designed layers. One of these detectors is the Large Detector Concept or LDC, a group that has many European members, but also a large American and some Asian involvement.

FALC — What’s in the Name?

Kenji Saito shows FALC representatives superconducting RF cavity research being done at KEK.
I attended a meeting hosted by KEK Laboratory in Tsukuba, Japan on 19 November of the "Funding Agencies for Large Colliders" (FALC), previously known as "Funding Agencies for the Linear Collider." The change of names for FALC has caused more than a little consternation within the ILC community. At our recently concluded GDE / ECFA meeting in Valencia, Spain, FALC chairman Roberto Petronzio was directly asked about the name change in his opening plenary presentation. He responded with a rather general statement about FALC's mission and goals. This, however, did not put the issue to rest. Richard Wade, PPARC Director of Programmes and Chair of the FALC Resource Group, was even more pointedly challenged during the town meeting a couple of days later with a somewhat rhetorical question concluding that the name change indicates FALC is backing off from its raison d'être (e.g. the ILC). Today, I discuss a few highlights from the recent FALC meeting and give my personal view of what's in the name of FALC.
