Structures
f
A Tunnel for an NLC RF TestThe ETF ceclosure is mostly empty now
and that is good!
f
And Building for an NLC RF TestThe MP9 building is now being
used to make parts of the CMS detector for the LHC but it can be
reused for the ETF.
f
1.8 meter long NLC RF structureMade by the KEK lab in Japan and
tested at the SLAC lab in CaliforniaEach structure has 206 disks
see next slide
f
NLC RF copper disksEach disk has a 61 mm diameter and 8 mm
thickness.The electron or positron beam goes through the center
hole and unwanted energy is taken away in the four side
channels.
f
NLC Permanent MagnetInsert Shunt Quad on SSW stand by Volk
f
TESLA at DESY is also an e+e- OptionTESLA = TeV Electron
Superconducting Linear AcceleratorThe DESY lab is proposing an e+e-
collider. The accelerator is made of superconducting rf
cavities.The tunnel is about 6 meters in diameter.
f
Protons on protonsThe good news is:We know how to do this
standard techniquesThis gives us the energy frontierThis is the
path to discoveryQ1: Whats it all made of? Q2: How does it all
behave?
The bad news is:Continuing the standard approach costs too
much
f
LHC IR Quadrupole MagnetCold Mass OnlyInsert P. Schlabachs Slide
ASC 18 Sep 2000 Slide 3
f
LHC IR Quadrupole MagnetFermilab is making several high gradient
quadrupole magnets for the Interaction Regions at the LHCThis
quadrupole magnet is 36 inches in diameter and about 7 meters
long
f
VLHC - Low Field OptionG.W. Foster and V. KashikhinMay 2000
Test Stand for the Field Measurement
f
A Tunnel Vision for the VLHCThe low field is on the bottom, the
high field is on the top.The high and low field are shown in the
LEP tunnel as an example.The tunnel is real and is about 12 feet in
diameter.
f
Insert Ernies Comments on a vlhc
f
Insert Ernies 500 km pipetron map study
f
Muons on muonsThe good news is:Just another simple lepton just
like the electronBut heavier than the electronThey dont radiate
photons like crazyThey interact better (40,000 times better) with
HiggsQ3: How do particles come by their mass?The bad new is:They
only stay around for 0.000 002 seconds (or so)They spit out
electrons which then radiate like crazy
f
Insert Muon Collider Schematic from Word
f
Neutrino BeamThe good new is:All the muons decay to electrons
and neutrinosNever been done surprises probably in storeQ1, Q2, Q3,
Q4, Q4++
The bad news is:Not discovery, not simple So, maybe not
interesting?
Aside: Really global-sized experiments

And Into the Beyond ...The good new and the bad new is:Hasnt
been done before For good reasons, usually ...
One example is Plasma acceleration100 TeV center of mass and
...All the equipment fits on the Fermilab siteBut is costs too much
to operate At least using todays technology
f
Insert Lindas Plasma acceleration

SummaryThis is still fun.Q1: So what IS it all made of? andQ2:
How DOES it all behave? etc etc
There is still lots to do.Decades (in performance and on
calendars)The best ideas are yet to come ...
