If any Party breaches any duty under this Contract and knows or should have known about such breach, the Party shall notify and warn the other Party of possible consequences. If any provision of this Contract becomes or is declared null, ineffective, non-existent or unenforceable, then such nullity, ineffectiveness, non-existence or unenforceability shall not make the Contract null, ineffective, non-existent or unenforceable as a whole. In such a case, the Parties shall without undue delay clarify such a defective provision within the meaning of Section 553(2) of the Civil Code, or replace it, to the extent permitted by the applicable laws, by mutual agreement with a new provision, whose meaning is as close as possible to the intention of the Parties at the conclusion of this Contract.

Name: __________________ Position: Director Position: __________________ The purpose of the tender is to obtain photomultipliers for electromagnetic calorimeter ECAL which is being built as a part of a HADES experiment. The photomultiplier type has to meet certain minimal criteria in sense of detection properties, physical dimensions, material of the detection window and power requirements. The requirements are quantitatively summarized in the section “technical parameters” below. Short justification of the requirements will be given here. Content of the following text is also considered to be part of the required technical parameters. Requirements for the detection properties comes from the detected physical quantity – Cherenkov radiation with wavelength of 420 nm, which corresponds to the required wavelength in the spectral response maxima. Due to the low intensity of detected radiation, sufficient cathode luminous sensitivity (min. 50 µA/lm) and anode luminous sensitivity (min. 50 A/lm) are required. A good response linearity is required. The allowed deviation for pulsed signals has to be up to 2% for anode current pulses of 30 mA. Dynamic range of the photomultiplier has to allow to measure from single photons up to thousands of photons in pulse. The photomultiplier has to meet required time parameters – rise time (anode) and electron transition time in order to be able to handle high signal rates. The combination of sufficient anode and cathode luminous sensitivities and time parameters is also crucial for correct function of already developed read-out electronics. Dark current with a maximum allowed value of 65 nA is required in order to reach the required sensitivity and to meet the required signal-to-noise ratio. Required parameters of the power supply are specified based on the already existing high-voltage system. The current via the divider is limited by the amount of waste heat generated by the photomultiplier-divider assembly inside of the detection module. The physical dimensions of the photomultiplier are constrained by the space available inside of the detection module and by the solution of the mechanical fixture of the photomultiplier. The photomultiplier must have an overall high quality and reliability because it cannot be replaced after the assembly of the ECAL detector.
