Slide 1
SiD meeting Oregon Workshop, Nov 2010
Assumptions & history & goal
What is our goal/what are we trying to do….
Develop a concept for a detector for a
future e+e- linear collider
Develop the physics case with that
concept
Develop simulation & reconstruction
framework/tools
Form a “collaboration/group” to pursue
concept
Develop & possible execute a R&D program
we = SiD
Developed SiD concept for
quite a while.
Not part of original TESLA
proposal .
Serious boost ~2004 with
choice for ILC
Promises ~2007
……. ILC price tag dampened
……..
Describe all this in LOI in 2009
Be advocates for that concept, get it
recognized.
Ultimate
goal:
H.Weerts
Realize this detector at an
accelerator & do physics
Slide 2
This should remain our goal independent
of “external conditions/requirements”
i.e. where, which machine, when, by
whom
SiD meeting Oregon Workshop, Nov 2010
Status now…
At first
world was simple, develop SiD detector for ILC i.e 0.5TeV and lower
Three independent concepts were developed: ILD, SiD & 4th
LOIs were called for for each concept
All three concepts develop LOI and develop identity
After ILC LOI submission
CLIC CDR for ~2011
ILC continues
• RD sets up IDAG
• IDAG deliberations
• SiD validated as ILC detector
• ……..
• Next step DBD
• Struggle for resources worldwide
• Two validated concepts remain
independent plus R&D collaborations
• Start up CERN/CLIC group: LCD
• Use validated ILD & SiD
• One strong group works on both
ILD & SiD
• Use existing simulation & reco
frameworks
• Improvements
• Goal is CLIC CDR for now
We need to resist the splitting up of SiD, stay one
community/collaboration working together towards THE goal
(requires satisfying intermediate requirements like DBD, CDR +++)

Goal?
H.Weerts
Using “same” tools, continue
cooperation, improve & keep common
tools
Prove that SiD concept like detector can do physics at
0.5, 1 & 3 TeV in ILC & CLIC environment

Status of ILC_SiD_DBD
Andy White plenary SiD talk at IWLC2010
SiD Workshop in June 2010 at Argonne gave pretty good
overview of all activities for ILC & CLIC. More at this workshop
Despite difficulties in support there is an active “ILC” detector R&D program:
•
•
•
•
•
•
•
•
•
Vertex pixel/sensor development ( Chronopix, 3D)
Progress in Si only tracking algorithms
PFA improvement & detector optimization
EMCAL R&D on Si-W
DHCAL prototype ( 38 planes, 365K channels in
testbeam), other efforts continue ( all within CALICE)
MDI work continues
Improving simulation & reconstruction software
Defining benchmarks for 1TeV
………….
There is progress, even though ideally would like to see more.
Goals for ILC_SiD_DBD or in general DBD are still somewhat in
flux. How much more than LOI is it ?
H.Weerts

SiD meeting Oregon Workshop, Nov 2010
Status of ILC_SiD_DBD
Discussion with IDAG at IWLC2010 ( October 20,2010)
Compared to Beijing more optimistic picture; whining does not help, there
is a dialog between CLIC and ILC efforts, positive feedback.
There should be …. in my opinion

Assume there is a team to continue to work towards ILC_SiD_DBD, while
work on CDR continues and an effort increase after CDR is done

Overall improve ? Cost ?
Related to above

Confront performance, need to use
Tuned to higher energy, 1 TeV ?
Different classes: machine dependent, energy dependent, just
improvements; selection of benchmarks.

Slide 10
SiD meeting Oregon Workshop, Nov 2010
Towards ILC_SiD_DBD 2
Obviously differences in SiD version dependent on which machine
environment.
Different at 0.5, 1 and 3TeV ? Or compromise possible?
Need to be careful not to contradict each other.
Can we optimize certains aspect for all versions in future?
Can we agree ?
Should we start with 1 TeV benchmark process selection?
Like ILC or like CLIC( tune for higher cms) already done ?
There must be others……
We have never done an exercise like this, with very detailed simulation of
detectors & machines at different energies and environments.

Good discussions & exchange at IWLC2010,
participation of same individuals in all efforts; N.Graf
and J.McCormick visited CERN on tools
Slide 12
SiD meeting Oregon Workshop, Nov 2010
“Lepton Collider” R&D in US
White paper was submitted to DoE
HEP and to community.
Describes/outlines a R&D program
to combine all Physics & Detector
R& D on charged lepton colliders
under one framework/program.
This includes ILC, CLIC and MuC.
Next step:
H.Weerts
Write a proposal for a framework & funding request to establish
a Physics & Detector R&D program for lepton colliders. Establish
a management structure for this to deal with e+e- as well as
muons, a generic (driven by lepton colliders) dtector R&D
program, simulation & reconstruction tool development and
request support to participate in Physics studies in all lepton
colliders.
Time scale: ~Feb. 2011 for call by DOE for Collider R&D proposals
