MDT_driftR

Muon_

Reconstructed

R,

x,y,z Radial distance to anode wire of charged particle’s track passing through MDT. Ionization electronics accelerate towards the wire, initiating a charge avalanche and producing a signal. Drift radius computed from drift time by an auto-calibrated procedure

Eta, phi,

pt

, e, m

(~a few/event)

AntiKt4TopoEM

Jets

Eta, Phi,

pt

, e, m

Jets arise due to gluon emission as quarks travel.

F

ragmentation of quarks into hadrons before they can be directly detected. Cone shaped, and can be thought of as repeated 1->2 branching of quarks and gluons.

CaloEgamma

Eta, Phi, et

Electrons/photons deposit most of their energy in the electromagnetic calorimeter.

Showers from electrons are narrow, search for concentrated deposits

of energy. Match with track to distinguish electrons from unconverted photons

PixelRDO

x

,y,z

high granularity, high precision set of measurements as close to the interaction point as possible using silicon detectors (photon hits silicon, knocks electron out of place causing electron-hole pair

Demos

Demo 1-First Steps CMS: RT event simulator,

websocket communication, freq. modulation using eta coordinates of calorimeter hits for CMS data produced by converting ROOT files to .IG files in CERN’s

OpenData VMDemo 2- ATLAS/Pure Data (Constant): Swapping in ATLAS data and ATLAS data parsers, selecting key physics variables, streaming to Pure

Data (audio synthesis software)

via OSC

(networking protocol for audio syntehsis at a constant rateDemo 3: Pure Data Eta Scan: Rebuilding OSC engine so that messages are transmitted on separate threads, allowing for each message to be passed at a different rate dependent on eta coordinate of hit (when possible)…effectively scanning through detector in a 10 second sweep. More particle production at high eta becomes noticeableDemo 4: Pure Data: BASIC audio composition with RT Stream Enabled:

I played around with Pure Data a bit: jets are audible over pixel detector hits and MDT

drift radii in background. Demo 5: Stream to Icecast2

: Turn on streaming, and audio is available on web

Demo 6: Webpage

Temporary image iterator, embedding stream alongside image on page. Muon on/off available SOON.

Basic framework in place. Can now

Work on more robust

audio compositions,

put more thought into

p

hysics

parameters, speeding up system,

isolating audio streams,

switch to real event

stream,

graphics

ORIGINAL PLAN

Upcoming Schedule: Summary

Website UI enhancements, add feature to listen

to individual particles, real time, synchronized image rendering, additional audio composition

LATE

FEBRUARY

EARLY MARCH

LATE MARCH

APRIL+

Define/execute on larger vision for project

Hook into real ATLAS data stream, additional testing/composition/speed up

LHC Turn On (Spring break at CERN to launch initial product in tandem?)

Physics Tool (?)

ToDo

: Get abstractions in place so that tool can be used with any real time data (CMS? AMS?)

ToDo

: Anyone can compose or perhaps even DJ in real time

Maybe an instrument attachment (sticker?) reading in RT physics data?

Embed More robust physics

in audio, practical tool for physics analysis?
