“…The Argon arc lamp is a free-burning DC powered device [101]. The pressurised argon gas (with approximate pressure of 7-10 bar [102][103][104]) enters at the cathode end, swirls along the central core until it exits at the anode end. In order to cool the arc edge, a sheet of water is created by swirling a high flow rate water vortex along the inside quartz tube wall with pressure over 60 bar at the inlet [108,110], as shown in Fig.…”

Solar simulators are used to test components and systems under controlled and repeatable conditions, often in locations with unsuitable insolation for outdoor testing. The growth in renewable energy generation has led to an increased need to develop, manufacture and test components and subsystems for solar thermal, photovoltaic (PV), and concentrating optics for both thermal and electrical solar applications. At the heart of any solar simulator is the light source itself. This paper reviews the light sources available for both low and high-flux solar simulators used for thermal applications. Criteria considered include a comparison of the lamp wavelength spectrum with the solar spectrum, lamp intensity, cost, stability, durability, and any hazards associated with use. Four main lamp types are discussed in detail, namely argon arc, the metal halide, tungsten halogen lamp, and xenon arc lamps.In addition to describing the characteristics of each lamp type, the popularity of usage of each type over time is also indicated. This is followed by guidelines for selecting a suitable lamp, depending on the requirements of the user and the criteria applied for selection. The appropriate international standards are also addressed and discussed. The review shows that metal halide and xenon arc lamps predominate, since both provide a good spectral match to the solar output. The xenon lamp provides a more intense and stable output, but has the disadvantages of being a high-pressure component, requiring infrared filtering, and the need of a more complex and expensive power supply. As a result, many new solar simulators prefer metal halide lamps.

Solar electrical and thermal energy research groups have focused on developing novel technologies and on improving existing renewable solutions. In 2014, the global combined installed capacity of solar hot water and concentrating solar power (CSP) was 410.4 GW, representing 8% of the world's renewable energy sources [4].The transient nature of solar energy represents a critical challenge for technologies testing. Outdoor experiments are carried out in real but uncontrollable environments. For example, incident solar energy levels are highly dependent on atmospheric conditions and sky clarity over time [5]. Therefore, achieving

“…5 shows the distributions of the deposition mass flux of the W vapour on the inner bulb wall. Equation 9gives the deposition mass flux of the W vapour (9) where uth is the thermal velocity of the W vapour [m/s]. The evaporation rate of the W vapour increases almost exponentially with the electrode temperature [26].…”

“…Kr arc lamps are used as the pump in solid-state lasers [8]. Ar arc lamps can be used to thermally processes semiconductor wafers [9]. During operation of the arc lamp, the temperature of the tungsten electrode reaches a value around the melting point of tungsten, leading to evaporation of the electrode material.…”
