1987 SLC Construction
of physics program using the SLC
is the first detector at the SLC Interaction Point
11: First Z decay at SLC observed by the MarkII detector. This is the
first decay of a Z to quarks ever observed.
MarkII scans Z resonance to determine its mass and width
6-13: Europhysics Conference on High Energy Physics, Madrid.
MarkII presents result that number of neutrinos is less than
3.9 at 95% confidence level.
1991 SLD replaces
MarkII at the SLC Interaction Point
SLD has first
1992 SLC Commissions
Polarized Electron Source. Polarization is 22%.
May 2: SLD
observes first Z decay from collisions of polarized electrons
with unpolarized positrons
1993 Polarization of electron
beam improves from 22% to 63% by using a
strained GaAs photocathode.
1994 Polarization of electron
beam improves from 63% to 75% by using a thin
100nm-thick active layer of strained GaAs as the photocathode.
1996 SLD installs an improved
CCD vertex detector with over 300 million pixels.
1998 SLD completes datataking
on June 5.
1999 SLD request for further
datataking is denied due to lack of available funding.
1999 Marty Breidenbach
awarded Panofsky Prize by the APS "for his many
contributions to e+e- physics, especially with the SLD detector at the
Stanford Linear Collider. His deep involvement in all aspects of the
project led to important advances both in the measurement of
electroweak parameters and in accelerator technology."
