Recommendations
Professional Development
Modify traditional labs to inquiry experiments
Inquiry
Incorporate lab journals and other writing tools
into science curricula
Writing
Provide training to enhance current instructional
techniques into curriculum

Allow for grades 6-12 to discuss detailed
curriculum, learning processes, and instructional
methods Coordinate math-related instructional
tools with concurrent math instructors

Logbook Usage in High Energy Physics Experiments

Logbook Usage

• Permanent record of decisions, actions, results
• Scientific Diary
• Maintains ability to reproduce results
• Details change during different phases of
  Experiments
• Design
• Research Development
• Construction
• Data taking
• Analysis

Necessary for the Scientific Method to
functionNOT a Mickey Mouse exercise
Examples from three situations

• E605 group that discovered the b quark
• D0 experiment co-discovery of top quark -from
  pre-proposal through hardware upgrade and current
  publications (1982-2007)
• QuarkNet (high school cosmic rays)

10
E605 high pt particle productionb quark
discoverers try to find top
Early Analysis

• Data reconstruction electron and muon both
  produced.
• Use data to predict of e-mu expected

Event Display
Test run to select e-mu events found none. Saw
only 23 fakes and 1 mu-mu, that is an Upsilon
11
E605

• Work in progress! Not a pretty summary
• Keep track of all effort. When a mistake is
  found. Dont erase, just cross out.

12
D0 Experiment

• 600 physicist collaboration (20 countries)
• Each physicist keeps his or her on record of
  work.
• The experiment maintains huge electronic data
  sets of planning, data taking and analysis
• Lets look at several ways logbooks are used.

D0 beginnings proposal 1982Design of
scintillating glass and torroidal magnet-
Technology rejected in favor of Uranium and
Liquid Argon
design
Some design ideas are replaced with better ones.
However, a magnet was proposed again in 1991 and
added in 2000
14
Sample calculations

• How do different designs
• (scintillator or Pb-glass) compare?

15
D0 simulation trigger design (1992)
Beam View of inner detectors

• Simple picture of tracks, preshower, calorimeter
• Electron trigger study
• 2-jets background
• FIRST realization that events with fake electrons
  can be rejected if Jet2 crudely found to be
  opposite. Careful pointing is not necessary

D0 and Accelerator data taking

• Start of Shift Notes  Shutdown continues. Feeder
  46B outage today at 0830.  - jck
• 081201-GV has asked us to restore all of the MI
  crates today. - jck
• 081509-  Roger Zimmerman has given permission
  for Richard Rebstock to escort an individual into
  the MI stairwells.  - fish
• 081810-  Fire testing at MI-50. Disregard
  alarms. - je-- Fri Oct 5 094938 comment
  by...je --  MI-50 fire testing complete. Be aware
  that a code 1 trouble alarm is still alarming.
• 081917-  MI is in the middle of a restore for
  all crates on MI link using file 966. - je-- Fri
  Oct 5 085519 comment by...CE --  Restore has
  completed successfully.
• 083051-  FESS reported Feeder 46 B power outage
  is beginning. We notified cryo.  - fish
• 083410-  B0A service building pond pump has
  quit running. This may be due to the 46B power
  outage. We are investigating.  - jck-- Fri Oct 5
  083604 comment by...jck --  
• Duty mechanic has been informed.
• --Feeder 46-B feeds F0 B0 and D0.
• This alarm will naturally appear with the power
  outage.-- Fri Oct 5 090710 comment by...jck
  --  
• Duty Mechanic confirms that the pond pump is out
• due to the Feeder outage.
• 084327-  DS called to inform us that the 100
  rack
• in the MI31 control room was out of power
  possibly due
• to a tripped breaker. This was causing network
• problems due to some switching hardware in the
  rack. Power has been restored.  - jck
• 085602-  DJ has permission to escort MB as a 1
  on 1 ODH escort into the Tev.  - fish
• 090309-  Sali reports that he is done pulling
  vacuum equipment from F-Sector. - CE
• 100232-  Code 5 at MI-10... ops are
  responding. - CE-- Fri Oct 5 102826 comment
  by...je --  The person involved had a medical
  procedure yesterday which introduced a
  radioactive isotope into her body. Doctors told
  her that the isotope would decay by today. Rad
  safety re-frisked her after a few minutes and
  found that the gloves had decayed and her hands
  had not. This indicated that the radiation was
  from the medical procedure rather than site
  contamination. The fire dept 1099'ed the
  incident. Subject was working 100 ft from the
  MI-10 entrance.

D0 Analysis

• Usually analysis is done within 5-6 person group,
  with reports to 50-person physics group.
• Logbook notes track data analysis, ideas , data
  tapes processed, plus comments from colleagues.
• Code is incredibly complicated requires online
  documentation because most is shared.

Analysis results and new plans
From August 14th Analysis results of Glenbrook
student study. Worry about several data points,
plans for more code and new data taking

• 400 cm point seems larger than expected from
  other points. Measured in two different periods.
  Second is not normalized yet but pattern will
  remain?
• Vasu discussed WIMP plan with me. She does not
  have a root tree constructed, but does have an
  I/O section done based in root. She offered to
  work with Mario to finish filter in a few days.
  Mario already has an input and first filter
  written in C that works. When checked that a
  second hit event does indeed pass our filter.
  Hes working on raw event output. Hes working
  on a UIC linux cluster but will migrate to
  dezero.phy.uic.edu where we will save all of the
  data.
• SG stopped by to pick up his array. He says that
  his kids might be interested in Moon. He has a
  remote control telescope stand that would follow
  the Sun/Moon trivially! He also mentioned that
  he has run in 40 marathons! No wonder hes able
  to stay with teaching physics.
• Tested Vasus profiling option on scaling_200cm
  file. Binning is weird, but it did show that
  first hits and second hits have different widths.
  Should redo with a WIMP file (once my PC is on
  AC power). Maybe Vasu can write out a histogram
  with 5ns binning from zero to 300ns. It was
  confusing to see negative entries.

Summary

• Same logbook record approach works for cosmic ray
  studies in class and 20-year long HEP
  collaborations.
• Must keep track of experiment, provide record and
  keep your thoughts organized
• Specific logbook form depends on situation, but
  nothing beats the graph-paper logbook for
  individual experimental efforts
• Its amazing how often we revisit ideas from a
  decade ago. You never know when todays idea or
  measurement will lead to future breakthroughs.
