IceTray simulation V1 status

What can we do with SIMULATION pacakge now?

What need to be done toward next version updates from the user side?

What we can/cannot do

We can simulate muon/electron charged/neutrino events with IceTray

We can reconstruct the simulated events

We can store the reconstructed results in root tree format

but we can not store simulated event (is coming)

The box is not closed: An overview of version 1

input/output of each module is only things

you need to care about for module development

common to real data

More on what we can/can't do now

systematic study Ex: throw/reconstruct simple muon track, electron cascades to study

reconstruction efficiency position/direction dependences

energy dependences of effective volume

reco algorithm study

study two down going muon events

study contained/non-contained

add amplitude and width parameter etc...

we can't,

change geometry in good way

fill realistic calibration

no amplitude/width implemented (?)

weighting not fully implemented etc....

Can study background corsika events

signal anis events with waveforms

detector/simulation performance test with simple-muon

practice with muon-llh-reco with linefit seed

DEMO: Throw muon, create electron cascade of desired/random position/length/energy

once you set up, to run is as easy as typing a command line of

root -q 'sss_linefit_muon_llh1.C(5, 5.0,"test.root")' etc.

Event Reconstruction 1

randomly thrown good/long muon track

reconstruction code: simple-seed/linefit + muon-llh-reco

reconstruction (fit convergence) efficiency ~ 65% highly depend on track properties

try seeds (JAMS, linefit, dipolefit)

MC Truth Energy

MC Truth Nadir

MC Truth Azimuth

muon reconstruction

x-axis: MC Truth Azimuth

y-axis: MuonLLH reco Azimuth

x-axis: MC Truth Nadir

y-axis: MuonLLH reco Nadir

Event Reconstruction 2

randomly thrown electron cascade near the centre

reconstruction code: cfirst + cscd-llh

x-axis: MC Truth z-position

y-axis: cfirst seed z-position

x-axis: MC Truth z-position

y-axis: cscd-llh seed z-position

red: cfirst seed z-position

black: cscd-llh seed z-position

In Short Term:
towards official simulator

We need to store the simulated data!

comparison with AMASIM

Implement the stuff we can not do now

photonics, detector simulation improvement

code which runs faster/better memory management

reconstruction tests

There are still so many things to come, but it is working and ready for further testing!
