<div>Electronic Log for Fernando Franco Felix.<br />
==To do== <br />
<br />
* Confirm with Hamamatsu the values of the minimum measurable intensity (P_min) and the maximum linearly measurable intensity (P_max). Hamamatsu has been contacted and the data to confirm given, awaiting response. <br />
<br />
<br />
===Correct presentation===<br />
<br />
* Send corrected presentation<br />
<br />
===Photodiodes===<br />
<br />
* Investigate how to calculate the intrinsic voltage<br />
<br />
===Others===<br />
<br />
* Investigate about signal theory to determine what would be the smallest current detectable while using all significant bits<br />
<br />
* Investigate how CT scans detect photons, since it seems to be similar to what we are doing<br />
<br />
* Design the circuit diagram of how would the photodiodes and the DDC1128 be connected<br />

===Progress report===<br />
<br />

<br />
* Explain what is Proton Therapy and why it is promising<br />
<br />
* Explain why there is a Bragg Peak and why calculating its precise location is vital<br />
<br />

<br />
===Others===<br />
<br />
<br />
* Investigate about signal theory to determine what would be the smallest current detectable while using all significant bits<br />
<br />
* Discovered that there are many conflicting definitions of the quantity known as "Noise equivalent power" and identified the one used in the Hamamtsu data sheets [10] [11] [http://www.iram.fr/~leclercq/Reports/About_NEP_photon_noise.pdf]<br />
<br />
* Used the appropriate definition of NEP to make a better calculation of the Minimal Detectable Signal<br />
<br />
* Read the DDC1128 data sheets to determine the largest possible signal by having the photodiodes connected to it as well as the largest amount of protons per second we could use<br />
<br />
* Investigated the spectrum for the para-Terphenyl and POPOP used in the scintillation plastic directly from the source "Handbook or Aromatic Molecules", identified the version of para-Therphenyl that best matches the spectrum reported by NEMO (4-(3,3-Dimetylbutoxy)-para-Terphenyl) and transformed the graphs into numerical data to produce a total spectrum and determining which one will be our primary wavelength<br />
<br />
* Sent Texas Instruments the required documents to sign NDA with TI to get the full Data Sheet of the DDC1128 <br />
<br />
* Read the basis of Proton Therapy, why does the Bragg Peak happen, how it can be used to treat cancer, red about the different kinds of proton beams and how do they work <br />
<br />
* Investigated how photodiodes work, from a photon reaching the photodiode to the generation of a signal<br />
<br />
* Investigated noise in photodiodes, how it is produced, how to reduce it, and how to detect a signal despite it, estimating the minimal detectable signal<br />
<br />
* Calculated the expected signal from a single proton entering the scintillator <br />
<br />
* Talk with Hamamatsu representative<br />
<br />
* Establish the criteria for which photodiodes we can use and make a list of which ones fulfill them<br />
<br />
* Make a table of the relevant characteristics of the photodiodes of interest<br />
<br />
* Investigated how Scintillation works, how photons or charged particles produce scintillation and why aromatic molecules are so useful for it<br />
<br />
* Investigated how the Analog to Digital Converters Work<br />
<br />
* Read about how to connect photodiodes to ADC<br />
<br />
* Contacted Texas Instrument about signing an NDA to get the full data sheet of the DDC1128<br />
<br />
* Make presentation<br />
<br />
* Give presentation<br />
<br />

<br />
* Sent Texas Instruments the required documents to sign NDA with TI to get the full Data Sheet of the DDC1128 <br />
<br />

<div>Electronic Log for Fernando Franco Felix.<br />
==To do== <br />
<br />
===Correct presentation===<br />
<br />
* Specify that the emission reported by NEMO matches with 4-(3,3-Dimetylbutoxy)-para-Terphenyl, but that we cannot be sure for certain because it is protected IP<br />
<br />
* Use more text to explain how the calorimeter works and its purpose<br />
<br />
* Rewrite presentation considering that is is for me to understand<br />
<br />
* Send corrected presentation<br />
<br />
===Photodiodes===<br />

<br />
* Used a apropiate definition <br />
<br />
* Investigated the spectrum for the para-Terphenyl and POPOP used in the scintillation plastic directly from the source "Handbook or Aromatic Molecules", identified the version of para-Therphenyl that best matches the spectrum reported by NEMO (4-(3,3-Dimetylbutoxy)-para-Terphenyl) and transformed the graphs into numerical data to produce a total spectrum and determining which one will be our primary wavelength<br />
<br />
* Sent Texas Instruments the required documents to sign NDA with TI to get the full Data Sheet of the DDC1128 <br />
<br />
* Read the basis of Proton Therapy, why does the Bragg Peak happen, how it can be used to treat cancer, red about the different kinds of proton beams and how do they work <br />
<br />
