Hi, I'm new to the list and just joined. A friend and I are brainstorming ideas for an experiment at high altitude on board a near-space balloon payload at 20...
Hello Hannes ! How are you ? I want to tell you that last week I was to Geneva at C.E.R.N. I visited the largest detector of muons from Earth. His name is...
Hi Bogdan! ... Thanks, fine again! :-) How are you ? ... Very cool! 1.5 years ago I saw the ATLAS still being on the surface and under construction. Must see...
Hello Bogdan, I'm posting here...not to upstage any later replys by Hannes, but to offer potential solution to a problem? It sounds like your VIDEO file(s) may...
I'm working on building a high altitude (~100,000ft/20 mi altitude) cosmic radiation experiment. Obviously at this altitude muons will be few and far between....
... Hi Andrew! First of all, use all information on the web with caution, especially info from my sites ;-) Seriously, I'm currently trying to figure out a...
... That was actually my second question -- would a scintillator work ;) ... Well, that won't be a problem for me, as I'll be using batteries anyway. But I...
Hi guys! I worked an a 6 weeks internship on ATLAS 2 years ago and visited CERN them for a few days. Just a few days ago my current supervisor was showing us...
Hello All ! The photos and movies are now to a ftp server that is now in revision. As soon as I get them from there I put them to photo section of our group...
Hi Andrew! Andrew wrote: [...] ... Not working yet actually ;-) The "old" method of reading the detector signal (100k resistor) doesn't work, since the flat...
Hello, Does anyone have any experience with attaching a GPS timestamp to an event counter? Refer to http://homepages.slingshot.co.nz/~geoff36/gps.htm for an...
... Hi Dan! Cool link! Thanks! Just a few thoughts on such precise timing: * what's the precision on GPS timing anyway ? * you need a real time OS to maintain...
... Good questions, Hannes. I would like to throw one out for discussion also: What is the timing requirement for timestamping events in (enter your...

Hi Hannes: My current project is a Precision Clock (it's a thing I've been working on for a few years (on and off). For a look at the current version see: ...
... With no fancy calculations, the one pulse per second signal gives a place to start: time in whole number seconds since midnight UTC. With the full GPS...
Hi Brooke, One could use the time stamp method to detect events in coincidence although spatially separated, saving the need for conventional coincidence...
Hi Yum: The limit to resolution for my Precision clock is the frequency of the source used for the instruction clock of the micro controller, and the clock is...
Hi: Is it really necessary have the reply email address set to No Reply? With this setting any reply automatically is bounced. Most of the Yahoo groups do NOT...
... Hi Brooke! I'm quite busy now, hence I haven't replies on the time stamp thread yet. In my email client, the reply goes just right back to the list: ...
Ciao Joseph! Come stai ? :-) ... Well, actually I have been planning to just use DCF77 (time signal from Germany - like WWV(?) in the US). Since the muon event...
Ciao Dan! Daniel Friedman wrote: [...] ... Ahh, thanks. I was actually guessing that it must be in the ns range. ... Agreed. See my previous email for my 2...
Ciao Brooke! ... My current plan for your scenario is the following: I'll use a ATmega16 microcontroller with an interrupt service routine. When an interrupt...
Main interest is the Muon Detector. http://www.lbl.gov/abc/cosmic/ Anyone done anything with this? Don "We are all born ignorant, but one must work hard to...
Ciao a tutti! Free access to the "online journals of the Royal Society" for two month http://www.journals.royalsoc.ac.uk download as much PDF's as you can! ...
YAHOO web services doesn't behave like it did in the first days. So message posting, notices, etc. might take a little longer than expected due yahoo's ...
Very interesting that it took a return to older technologies to find the particle. Sometimes, newer is not better. And you should always have more than one...
